Tips on Using “Maps Past”

In Maps as a Resource: New Zealand’s “Maps Past”, Part One and Part Two, I demonstrate ways in which the “Maps Past” website provides maps of interest to researchers. The following is a step-by-step introduction to using the website for those who might find it useful.

Step One: Go to The following (or something similar) is likely to open as the home page:

01 home page

The next two steps are aimed at getting rid of unnecessary material from the screen before zeroing in on a location of interest.

Step Two: Get rid of the “Select basemap” pop-up menus by clicking on the “x” on it (circled in black on the image below): 

02 home page base map pop up

Step Three: Remove the text material from the lefthand side of the page by clicking on “Mapvv” (partly circled in black in the image below) which is on the righthand margin at the top:

03 home page margin

This then should leave you with a map of New Zealand  and seven icons at the left top of the page:

04 home page simple

The seven icons are:

05 icons

From left to right:

White plus and minus signs on blue background = Zoom in/Zoom out.

Three layers icon = “Select basemap” = Brings up list of 14 options, most of them decades.

Cog icon = “Map options, Coordinate format” = Brings up list of 11 options.

White i in blue circle = “Show mapsheet details for current series when you click on the map”.

Clipboard list with white i in blue circle on bottom right corner = “List all available mapsheets at point you click on the map”.

Magnifying glass with three arrows = “Zoom to extent of current mapsheet/series”.

Two chain links = “Show URL of currently displayed map”.

Below I will discuss the use of four of these icons – the first, second, fourth and fifth. I have found that I can achieve what I want through using these four. 

Step Four: Use the “Zoom in” icon (white plus sign on blue background at top left of screen) to zoom in to the location you want to examine. You are likely to also need to move the map to bring your intended location to the centre of the screen – move the cursor to somewhere on the screen, click and hold, then move the cursor – this will move the map. I have chosen to zoom in on Riverton at the bottom of the South Island (see below). At the bottom right hand of the screen are some figures, the scale of the map on screen, the map sheet or series, and co-ordinates of the cursor. In this case, for example, there is “Scale = 1 : 27K” (27K = 27000) and “NZTM2000” map series. This information may or may not ever be of use to you.

06 Riverton11


Step Five: Once you have zoomed in to the location you want, at the scale or level of detail you want, you can then click on the “Select basemap” icon (three layers icon) at the top left to choose which map you want to see.


07 Riverton select basemap start1111

I decided to try to find the earliest map. I clicked on the fourth last map “NZMS13 1899”. The list then disappeared and the screen went blank. This means such a map does not exist. I clicked again on the “Select basemap” icon to bring the list of maps up again, and clicked on “NZMS13 1909”. Same blank result. When I next clicked on “NZMS13 1919”, the following map came up:

08 Riverton 1919

 The 1929 map was the same. The 1949 map was not at a good level of detail:

09 Riverton 1949

But the 1959 map was a good one:

10 Riverton 1959

And we could go on, choosing more recent maps or the air photo…

Step Six: Finding out what maps are available for the location. To do this, you click on the icon of a clipboard list with white i in blue circle on bottom right corner – this is to “List all available mapsheets at point you click on the map”. This icon turns green when you click on it. You then click on a point on the map and a popup list appears which you can scroll down. This lists all maps that have been published or are available for this location. 

11 Riverton map series avail

The earliest map listed for Riverton is Series: NZMS13 Sheet: SD58, Printed: 1910. This will be why no map came up earlier for 1909 but one came up for 1919 when I was using the  “Select basemap” icon. 

Step Seven: Finding out which map you are viewing. When a map is on the screen, you can use the icon of the white i in blue circle = “Show mapsheet details for current series when you click on the map”.

12 Riverton map being viewed


This icon also turns green when you click on it. You then click on a point on the map and a popup list appears which identifies the map that is being shown. In the case above, the 1910 map is identified even though the map came onto the screen originally when I was using the “Select basemap” icon and had chosen “NZMS13 1919” from its menu list. In other words, the decade menu list that appears when you click the  “Select basemap” icon does not mean that the map that comes up was published the year shown (1919 in this case) but it may have been earlier (1910 in this case).

It was the use of these steps that helped me obtain the material discussed in the Posts Maps as a Resource: New Zealand’s “Maps Past”, Part One and Part Two, and which has proved useful in my local history and family research.

Maps as a Resource: New Zealand’s “Maps Past”, Part One

Over the past few months, I have been doing some research on the district in which I grew up, around Waikaka in Southland, and on the members of my family who first settled there in the 1870s and their involvement in farming and gold dredging. This is an area I return to from time to time, and from which I collect stones. Recently I have been seeing what is available online in terms of historical maps. One very useful website I have discovered is “Maps Past” which, oddly enough, does not have a page giving details of who has produced the site.

The opening page of “Maps Past” presents a map of New Zealand, and it is possible to zoom into any particular part of the country. Then you are able to click on different dates (set as decades, starting at 1899 with only 1939 not available) and bring up maps from that time of the area on your screen. Sometimes as you go from one decade to another, the same map will be presented, depending on when new maps were constructed. I will illustrate this by showing the different maps available for Waikaka and the area to the south which includes “The Mains”, the farm on which I grew up. 

There are nine different maps that are available for the Waikaka area, one of which is a recent aerial photo. The following are thumbnails that will expand when clicked on (there is a “View full size” underneath the expanded image in the viewer – you may need to scroll down to see it):

This first part of this Topic will deal with the first four of these maps. The other five are dealt with in Maps as a Resource: New Zealand’s “Maps Past”, Part Two. Note that the following map images are not expandable – use the thumbnail above for a more detailed view of any of the maps.

The first map is for the decade ending in 1899. It is actually from a map of the Chatton Survey District published in 1888:

001 - NZMS13 1899

It is interesting to note the areas around Waikaka designated as “Auriferous Reserve” and “Gold Reserve”, and the area of dots to the southeast of the town labelled “GOLD WORKINGS” (though it is very difficult to see this label). Gold had been discovered near Waikaka in 1867 and the following 60 years saw various phases of panning, mining, sluicing and dredging. Section 30 of Block 3, located directly south of Waikaka, just below the centre of the map, was bought in April 1876 by Hugh Paterson, my great-great-grandfather. This was the beginnings of “The Mains” farm.

The second map is for the decade ending in 1929. It is actually from a map of the Chatton Survey District published in 1929:

002 - NZMS13 1929

One noticeable addition to the map is the Waikaka Branch Railway, constructed in 1907 and 1908 to provide faster transport of agricultural produce to markets. It was the last of the branch lines authorised in northern Southland. In “Waikaka Saga” (1962), Evans refers to James Paterson, my great-grandfather, as one of the “well-known characters” (page 191) on the train, one of the local land-owners who traveled to Gore (about 25 kms away) on Saturdays to do business. “All of these men were intensely interested in politics, religion, world affairs, agriculture, and so on. Even before the train had pulled out of Waikaka station, the argument had started and they had forgotten to buy their tickets, and so scrambled on at the last moment…[They] used to have great arguments and discussions on the train, so much so that it became quite an institution.” The railway line ran through “The Mains”, with the Pullar Railway Station (Siding) located just on the southern boundary of the farm. It is reported in the Mataura Ensign on 27 July 1909 that James Paterson was given 50 acres of the Waikaka Commonage (mining reserve) to compensate for part of The Mains being cut off from access to water. Due to competition from roading, the Waikaka Branch Railway closed on 9 September 1962 (Wikipedia). 

In the middle of “The Mains” was a rail bridge across the “Waikaka Stream”. Soon after the line opened, Leonard Paterson, my grandfather, traveled to high school in Gore by train which would slow down by this bridge so he could hop on (“Paterson Family Reunion 2002”, page 24). He was also a passenger on the final train from Waikaka in 1962, standing sixth from the right in the photo below, his wife Annie to his right. They had retired to live in Gore in 1957.

The third map is for the decade ending in 1959. It is actually from a map of the NZMS1 series published in 1946, the S161 “Heriot” Sheet. This is a topographic map, showing relief, using contour lines, whereas the previous two are land survey maps primarily concerned to present farm land boundaries. 

003 - NZMS1 1959

This is the same map with the approximate boundary (in black) of “The Mains”:

003 - NZMS1 1959 - Copy

Note that the road running east of the boundary of “The Mains” is called “Turnbulls Road” (after a prominent family) . In later maps this becomes “Turnbull Road”. Note also that “Tailings” are indicated in “The Mains” to the left of the railway line. Elsewhere on the map is reference to “Workings” and “Old Workings”.  These are old gold dredge tailings and sluicing areas. Most of the flat land along the west and east branches of the Waikaka Stream as far south as McNab (21 kms) was heavily dredged between 1896 and 1926. As reported in an entry on “Gold-Dredging in the Waikaka Valley” in “The New Zealand Mining Handbook” of 1906, “By means of a separating-box soil and sand are distributed over the tailings, which are left perfectly level, and when sown with clover and grass yield excellent grazing” (page 198).  In “Golden Reflections: A History of Waikaka Valley” (1992), J.F. McArthur reports: “Dredging operations disturbed the whole valley floor, which was completely turned over to the depth of 12 to 14 feet [3.7 to 4.3 metres]” (page 366). He refers to how the dredges lifted the top soil of the area about to be dredged and placed it, using an extended chute, over the area previously dredged (page 367). It has been claimed that much swampy land was improved considerably by gold dredging. Certainly I remember the tailings on “The Mains”, although prone to drying out in summer, provided great free-draining winter grazing and grew excellent lucerne (alfalfa). 

The fourth map is for the decade ending in 1969. The “Maps Past” website indicates this is based on the NZMS1 series “Heriot” Sheet published in 1957, again a topographic map:004 - NZMS1 1969

However, only parts of the railway line are indicated even though it was not removed until after 1962, when I remember my father dismantling the section that ran through “The Mains”. Maybe this is actually based on a later map. A new “Old Workings” label appears on the map to the south of “The Mains” boundary. These old gold dredge ponds on the Waikaka Stream existed even prior to the previous map.  I used to fish for trout there often as a boy, and we called it Turnbull’s Dam as it is located on Turnbull’s farm (even though it is a couple of ponds through which the river flows rather than a dam). It is interesting to note on this map that the road in the south-east corner is called “Sandy Knowes Road”. On later maps this becomes  the “Kelso Maitland Road” before becoming “Glenkenich Road”. Meanwhile, the road in the north-east is on this map called the “Waikaka Kelso Road” (the “Kelso” part can’t be read on this segment) and on the next map is called “Sandy Knowes Road”. (On all maps, “Garden Gully Road” connects these two roads.) There is potential confusion here for local historians when local people or documents refer to Sandy Knowes.

This Topic is continued in Maps as a Resource: New Zealand’s “Maps Past”, Part Two, where the next five maps are discussed. Another Post sets out Tips on Using “Maps Past” to assist you if you are not sure what to do to get started in using the website. 

“Down to the Earth’s Core”: A Documentary

I recently saw part of an animated documentary on National Geographic about what can be found as you move from the Earth’s surface to its centre. “Down to the Earth’s Core”, a 90 minute film released in 2012, uses often spectacular computer generated imagery. An earthquake inside the San Andreas Fault is shown, along with an erupting volcano and bizarre cave-dwelling creatures. Earth’s extraordinary history is laid bare, layer by layer. A number of fascinating stories are told in the course of the journey downwards, such as how prehistoric forests became modern-day fuel and how dinosaurs experienced cataclysmic death. Eventually the planet’s super-heated liquid core is reached.

Some of the highlights for me are listed below, along with how many minutes they can be found into the YouTube video above: the Carlsbad Caverns of New Mexico, 240 metres below the surface (at 9.00 minutes); a cave of giant crystals, 300 metres deep (at 20.17 minutes); the layer of extraterrestrial iridium rock at 550 metres and its link to dinosaur extinction (at 25.45 minutes);  the accumulation of gold deposits nearly 2 kms down (at 34.22 minutes); the formation of amethyst quartz crystals at 3.9 kms (at 38.42 minutes); and how diamonds came to be, at 240 kms down (at 1 hour 8.40 minutes).

“The New Zealand Rockhunter” Magazine – 1972-2000


This magazine began life in 1972, “incorporating The New Zealand Lapidary”, a previous magazine that I have yet to find out much about.  I have been looking to access any of these “early” sources of information about rock hounding and stone polishing as there is no doubt much of relevance still to be found there. I have previously searched unsuccessfully online for any copies of “The NZ Lapidary” for sale and have only now realised that “The NZ Rockhunter” succeeded it. I have also just discovered that the Otago Rock and Mineral Club’s website has a link to scans of many of the issues of “The NZ Rockhunter”, the link being found on the New Zealand Geology Information page. Issues from the years 1972 to 1988 and 1998 to 2000  can be found here. A plea has been made for copies or scans of missing issues to be sent. The Otago Rock and Mineral Club’s website also has a section called “The Library”, organised by region, in which are posted a range of articles from “The NZ Rockhunter” and some other sources. This kind of information from many years ago can still be invaluable to rock hounds and stone polishers today.

“Step outside, take a look at the stars…”

Paradoxically, stones are in stars and stars are in stones. In his book The Planet in a Pebble: A Journey into Earth’s Deep History (2010), British geologist Jan Zalasiewicz tells the story of a pebble’s history, stretching back billions of years. In Chapter One, “Stardust”, he points out how, at the atomic level, a pebble is a microcosm of the Universe, made up of that which goes back to the singularity of the beginnings of everything: 

The pebble, in this respect, is as deep a mystery as is everything else in the Universe. How did the matter of that pebble, and of the…hills it was torn from, and of the world it sits atop – and of the Solar System and of the Milky Way, and of countless galaxies near and far – manage to unpack itself from a point: a ‘singularity’, as many think, of no size at all? (page 7)

A pebble is made of stardust and in it we encounter not only the depths of the Earth but also the heights of the heavens. Looking down is a way of looking up. Looking into a stone is also to glance across deep dark space and even time. In a stone we make contact with that which is closest to home as well as that which is furthest away. 

“Making Contact” by Bruce Cockburn

Step outside, take a look at the stars
Catch a glimpse of the way things are
Making contact…

Smell of sweet fresh oil on skin
When you move on me like the tide coming in 
Making contact…

So many ways to understand
One for every woman and man
Been that way since the world began

I hear the drumming of the surf and I have to dance
Stepping to the rhythm of circumstance
Making contact…

I feel so huge,  I feel so small
I feel so good I want to swallow it all
Making contact…

Making contact
Swimming in an ocean of love
We move together like the waves
Swimming in an ocean of love
Every night and every day
Swimming in an ocean of love
One world, one human race
Swimming in an ocean of love
One kiss from a smiling face
Swimming in an ocean of love
See that sign coming into view
Swimming in an ocean of love
Mother sea welcomes you
Swimming in an ocean of love
Making contact…

“Beach Stones” by Josie Iselin and Margaret Carruthers (2006)

This is a book celebrating the beach stone in its raw form. Josie Iselin is a photographer and installation artist from San Francisco. She has published seven books which focus on those forms in nature that can be found “at hand” and, in particular, at the beach. She explains in the “Artist’s Note” on page 139 of “Beach Stones”, about ten years previously she abandoned her camera and instead started to use her flatbed scanner to gain a different level of detail in her images. All the pictures of stones in this book are scanned. Margaret Carruthers is an Earth Science writer from Baltimore and confesses to having “a vast collection of rocks” (dust jacket). Among her other books is the co-authored”National Audubon Society First Field Guide to Rocks and Minerals” (2005).

“Beach Stones” is a reflective rather than an investigative work. Stones are objects of intrigue and contemplation. The book collects stones from around the world, including a pair from Greymouth in New Zealand. One review expressed disappointment with the book in that there was not enough information of each stone. But that is not its aim. Its aim is more to get the reader to “really look” at the stones, as Josie has done, and to speak of them in a way that arouses curiosity and leads to further personal engagement with beach stones.

 Physically, the book is 18 cm by 18 cm, consisting of 144 pages. Pictures of stones make up just over half of the book, and many of the pages of text contain just a few lines – the images of beach stones are its preoccupation. It is not expensive ( in New Zealand has it for sale at just under NZ$30). Every now and again, I enjoy spending time with a stone or three from its pages.

Birdlings Flat I: What the Books say

Birdlings Flat is a beach about an hour’s drive from Christchurch in the South Island of New Zealand.

Display in Birdlings Flat Gemstone and Fossil Museum

Lyn and Ray Cooper (1966), New Zealand Gemstones, Chapter 2 “Where to Find the Stones”: Birdlings Flat in Canterbury was, at one time, an excellent source for agates, but supplies are now much harder to find there, mainly because of the area’s close proximity to a large city and the swarms of collectors who have combed it over the past year or so. Good agates can still be found there, but the best time is immediately after a storm, when the sea has turned the surface stones over. (page 28) 

Mrs A. Niethe, “Gemstone Localities: New Zealand” in Bill Myatt (ed.) (1972), Australian and New Zealand Gemstones: How and Where to Find Them: Birdling’s Flat (it is named after the late Mr Birdling, who had a farm there) is part of the shingle spit, some 15 miles long, enclosing Lake Ellesmere. Half-a-dozen rivers along the coast to the west carry these gemstones from the hills inland to the sea. For millions of years the set of the current has swept the gravels north to pile against the basalt cliffs of the Banks Peninsula…  This is the Mecca of New Zealand’s rockhounds, famed for a variety of gemstones that reads like a geological dictionary. Coloured quartz of many types is the most common – jasper; chalcedony, mostly clear or grey or white, sard, sardonyx. petrified wood of various colours – a lot are fractured, after a while you only keep the perfect ones… Stones reached this beach from many parts of the South Island, presumably through glacial action in the ice ages. Rhodonite has been found here, quartzite, jasper from the Livingstone Mountains to the south-west; prase and plasma from the Hinds River, 60 miles away to the west, and true jade as Maori artefacts. Beware, this beach is extremely dangerous. Turning one’s back on the sea to pick over the rising bank of pebbles is almost involuntary, but it is very risky at Birdling’s Flat where the big waves knock you off your feet. (page 436)

Natalie Fernandez (1981), The New Zealand Rockhound, Chapter 5 “Locations”: Hundreds of rockhounds have cut their teeth on Birdlings Beach – just a short run from Christchurch. Here great rollers break on the stony shore throwing forward stones with a roar as the waves thunder up the steeply shelving beach and sucking them back with a clatter as the waves recede. You can look for your agates and jaspers well back from the water-line but they do not show up clearly unless you dig down, for only the surface layer is dry. More exciting is to hunt along the water’s edge. As a wave slides back an agate is spotted. You leap for it but miss as the next wave roars in, driving you back. You never see that agate again. The beach is steep and the undertow strong. The breakers are especially powerful in a southerly and on the in-coming tide. Few can play this game and keep dry. (page 14)    

Fernandez Birdlings Flat
“Birdlings Beach” following page 16, Fernandez, The New Zealand Rockhound

Natalie Fernandez (1981), The New Zealand Rockhound, Chapter 5 “Locations”: Birdlings Flat is 26 miles from Christchurch on the Akaroa Road. Shingle beach for 15 miles. There are still some pickings especially with a N.W. wind and an incoming tide. During a Southerly with rough seas the stones are sucked away again. A slight easterly with calm weather builds up the beach again. There is a strong under-current. The great rivers flowing into the Canterbury Bight bring material from inland to the sea. The current brings them north to be deposited where Banks Peninsula forms a barrier. Petrified wood, jasper, grey clear chalcedony, sardonyx, agate. In 1965 the beach was gazetted as a reserve. It is dangerous. (page 114)

“The Pebbles on the Beach” by Clarence Ellis (1954/1965)

This book was first published in 1954 (this paperback edition appeared in 1965) but in many ways it is the best book I have so far encountered on the topic of beach stones. It is 20 cm by 13 cm and has 163 pages. Published by Faber and Faber of London, it deals with beach pebbles in the UK but most of its content is relevant to many other localities. This is particularly so of the first four chapters about the beach processes that shape pebbles and the different kinds of  pebbles.

There are four colour plates of stones with accompanying interpretive diagrams labeling and describing each stone. Many of these stones can be found in New Zealand too. 

I bought this book for NZ$26 (including postage) through Amazon, and it came from Langdon e-traders, a UK charity business established in 2014 to employ and support young men and women with disabilities. 

Where Agates Can be Found in New Zealand

NOTE: 3 July 2019 – The mineralworld website referred below is no longer available currently on the internet. I have therefore included in square brackets below access to this material via the Internet Archive, as it existed in 2016-2017.

Mineralworld [see archiveis a website developed by Klaus Schäfer, [see archive], a German gemstone expert and jewellery-designer, who has done a lot of research and writing about gemstones, especially agates and jasper. He refers to his site as an “agate-almanac” – it is all about agates. An agate can be described technically as a translucent cryptocrystalline variety of quartz, a variegated chalcedony, characterised by colours in alternating stripes or bands, in irregular clouds, or in moss-like forms. Agates may have a wide variety of colour patterns and banding, with the many distinctive styles and patterns virtually making each agate unique. 

There are many pages on Klaus Schäfer’s website about agates worldwide, with a multitude of excellent and beautiful photos from a wide range of collections. Some of the information and articles are in German but there is much English material there as well.

Part of the website is called “Agates Worldwide” and has detailed descriptions of thousands of places where agates can be found. One page is the Index to the New Zealand material [see archive] where 28 locations are listed (such as Birdlings Flat, Hinds River, Nimmo’s Swamp, and Ward’s Beach). Click on a location and you are taken to a page with a description of the location and the agates that have been found there (usually written by NZ experts), illustrated with exquisite agate photos [NOTE: The Internet Archive very unfortunately did not archive these photos, but some agate photos can be found elsewhere on the archived site – click here for examples], four of which are below. The localities of origin of the agates in these photos are, from left to right: Nimmo’s Swamp, near Moeraki in Otago; Rangiatea Station near Mt Somers, Canterbury – this photo is by Malcolm Luxton who has recently published a book on “Agates of New Zealand” (see my comments on Luxton’s book in the section on Stone 11 in “Twelve Stones, Part Four“); Whitecliffs clay pit in Canterbury; and Gawler Downs Station near Mt Somers, Canterbury.

These agates were large enough to slice through so that their banding and internal patterns are shown to best effect. If agates are too small for this, they can be tumble polished like other small stones.
