While I was using GPS the whole time I was in NZ, really the only time I think one would have been useful - as opposed to going really old-school and hauling around a Rand McNally atlas - was in Auckland. Especially true for South Island, where you really don't need one to get around, even in Christchurch (IMO).
In other words - the free GPS map should be more than fine.
