When I look at contours on Google Earth, the coordinates do not match my new maps. I assume they are using the old system. Do I need to delete GEarth and reinstall, or am I missing something?

I think it depends on what you are comparing to. Google earth will be projected using a slightly different format than say, Linz.
I am not a techy by any means, but I do know that positions will be given on GE in a format that may not match what ever mapping you are using.
There are simple (ish) ways of converting though
Do you mean a different coordinate system, as in decimal degrees vs degrees minutes seconds vs UTMs.
Might just need to select a different format on the google earth
UTM on google earth still wont match NZTM though, will it?
Pass, hopefully someone here is into GIS.
Google earth only has a few preset coordinate options.
Nope, different projections.Quote:

If you want to use a GPS unit with google earth try setting the GPS to WGS84 coordinates, should be the same as google earth. Or just use something else like WAMS, like other people have said.
Are the new maps digital or old school folding type Lentil?
If they're digital and on a GPS, I agree the easiest would be to reset the GPS datum to match Google Earth, I had figured they were paper maps though.
NZTopo is a site i find good for getting GPS co-ords. Just remember to press the convert button to select your preference of nav setup if that makes sense?
WAMS all the way for me, as I like to toggle between the topo map and ariel pics. Much more accurate way of marking spots that just having topo alone.

Can you see the little grassy clearing
