Brent's New Zealand Street Maps for Garmin GPS are now available via his new site.
I use them with my Garmin Legend and Mapsource software but they also come with a DOS loader if you don’t have Mapsource. Until Brent made these available Garmin Worldmap was the only up-loadable mapping for Garmin GPS in NZ. Compare the level of detail in the screenshot from Worldmap with Brent’s Street Map (Version 3).
The street data is based on the LINZ database and with the assistance of partners at Where Are We Brent is also adding extra Points of Interest and other data. The older versions are still available to use with low memory GPS. The Legends 8mb memory can hold all the street maps for NZ. Adding the search data (find streets and intersections, POI) reduces this to about 1/2 of NZ. You can decide what to take as the data is split into different map sections so this isnt a big deal
