Wiki pages can be created. This is a quick test.
So in theory this is now a wiki page that other people should be able to edit and add info too.
Here’s a list of useful maps:
Historical Aerial Imagery for Canterbury
NZ Topo Map
Land Informatoin NZ Property Titles
NZ Petrolium & Minerals Ability to search claim numbers
Water Depths Map
Alexander Turnbull archives
Auckland Council Heritage Images
Maps Past
Digital NZ
National Library

Testing edit by other user - works!
