Ninthace, which maps did you use for NewZealand?
Mapping in NZ is not great compared with ours - sorry to any Kiwis reading. The NZ equivalent of our OS is LINZ. There is no Garmin equivalent to the Birdseye OS mapping imagery based on LINZ. I managed, with advice from sussamb to download Open Source maps of NZ with a Topo overlay onto my Garmin. It was not hugely successful as a map but it was usable.
If you have ViewRanger you can subscribe to LINZ mapping in a similar way to the VR subscription to OS in this country. You can subscribe monthly, it wasn’t a lot of credits. I plotted my routes in advance of my trip and saved the gpx files to OneDrive so I could pull down the traces to my phone when I wanted and when I had Wi-fi. I duplicated the library of traces onto my Garmin SD card as I did not have access to Basecamp during the trip. On the trip I used VR with LINZ as my main aid with the trace on Garmin as a backup. I recorded the.walk on both VR and Garmin.
You can buy paper LINZ maps but I did not bother as I had A4 printouts of possible walks anyway. Walking in NZ tends to be on trails which are usually well marked. You should be aware there is no equivalent system of public footpaths as such. Private land is just that.
Our best walk was the Tongariro Alpine Crossing. You will need to book it as it is a point to point walk and you cannot leave cars at either end for more than 4 hours. The route is well marked and there is a stream of people on it. Most people stay in the National Park and get bussed to the start. The buses have a system of accounting for you so you will not get left behind.
We are off to NZ again in Oct/Nov as Ninthace Minor as just produced a little Ninthace of his own. This time we will be based in Rotorua. Do you have a planned area to visit?
