In januari we are going to travel to New Zealand. Because we also want to do some caches there, it would be handy to have te roadmap of New Zealand loaded in our E vista. Is there a geocacher in New Zealand where we can load the roadmap? We arrive in Auckland at the 29th of januari and we are going to travel the eastcoast to Wellington (we have already seen the otherside 3 years ago).
