NZ topo50

Runs off satellites so don't need reception, also you don't have to have looked at the map while in reception in order for your phone to remember it.

Easy to overlay conservation land boundries ontop of topo map which can be very handy at times.

If you are not expecting any calls then switching to flight mode will stop your phone searching for a network which vastly increases your phones battery life.

I have found it to be a little out at times in heavy bush but generally its pretty good
