Water supplies.
I was told everywhere that the water was clean and that the locals drank direct from Wakatipu and the rivers running into it. I filtered all mine using my old Aquapure traveller, so can’t say whether the water was safe or not. I reckon that the thing to watch for is the places that use rain water collected from their roof, some places stated that this could be contaminated by birds and was not to be drunk, others didn’t bother and locals drank it without a thought. As a visitor, I didn’t want to risk even a couple of days’ off with a stomach bug. I drank the tap water in Christchurch without any problem, was told it was ground water, filtered everything else.
Security and safety.
I thought NZ was a safe place, and it may be, or not…according to a German I met who had been travelling there for eight months, North and South. He said South was safer, but that robberies from tourists camped in isolated locations on the North Island were fairly common. He had had people attempt to gain access to his vehicle at night while he was in it, including through deception, knowing he was in it. I had no problems, but the places I stayed were not isolated.
Re-supply.
Food is not as cheap as it is in the UK, but supermarkets in all the major towns will have everything a tripper could want in terms of food, toiletries, cleaning stuff, spare batteries (not sure about 123As) and the like. I stayed in a motel first and last night and left all my un-used stuff with them when I departed, they said they had a box of re-cycled supplies that they offered to people setting off in camper vans. I didn't know this and packed according to my experiences as part of a group travelling in Sweden, Norway and Canada, where to some extent, if you wanted it, you needed to bring it from home. Felt pretty stupid when I saw stuff I had given luggage allowance to sitting on NZ store shelves.
Fuel costs.
When I was there they were somewhere between comparable and cheaper than the UK. At the time, UK was £1.13 per litre ($2.42), while in Christchurch it was $1.92, in Greymouth $1.94 Hokitika $1.96 and Franz Josef $2.34. Auckland was $1.84
Navigation.
There is an excellent map shop in Christchurch.
http://www.mapworld.co.nz/ Make time to go there, they have more than appears on the web site. The other source for maps is
http://www.stanfords.co.uk/ in London, but be aware, the road atlases cost £24 in the UK, and $29 in NZ, making it worth while buying them once you are there, rather than paying double and then have them use luggage allowance on the way out.
I did toy around with my northern hemisphere compass, but it wasn’t reliable. I didn’t do anything that required a compass for navigation, but if you do, then look at buying a Southern Hemisphere adjusted one out there. Map World has them, and they are much more reasonable than buying one here.
After my locally purchased road maps, the best bit of navigational stuff I had was my smartphone loaded with View Ranger and City Maps 2 Go. Both of these allow you to load maps onto the device for use off-line, and are FAR easier to handle than messing with Google Maps off-line. View Ranger has 1:50,000 topos that show fence boundaries for all of NZ and you can get both regions and single tiles. Excellent tool. City Maps is good for marking locations of shops or camp sites. The built in index is a bit rubbish, but the maps are good. No turn-by-turn navigation on either, but honestly, in New Zealand, you don’t need it. Full satnav would have been good for me in in Auckland when I was running late for returning my rental car at 9:30pm and got lost, and maybe in Chirstchurch for about 10 minutes, but not worth paying extra for either on a phone or with a rental car. A passenger/navigator would have totally solved my brief problems. The other app worth having is the Rankers NZ Campsite app which can be downloaded for use without data coverage. Shows all the campsites, has reviews and ratings.

Coms
As I got off the plane in Auckland there was someone from Virgin Mobile holding a sign offering SIM cards for tourists. Something like $30 for a 4-week active card with a given amount of minutes and data on it. Didn't use anything like all of the allowance travelling by myself. Was able to check weather and send messages from a lot of places. There are some pretty good maps showing coverage in NZ. If you have line of sight to a town, chances are you will be able to get data. The west coast was the best example of this as you drop in and out of service as you go along.
Fishing.
I had heard that I needed to practice casting, so I took three hours of tuition followed by probably a dozen evening sessions on the green outside my house, much to my neighbours’ amusement. I tried to learn roll casts and single handed Spey casts along with aerial mends and other slack line presentations methods. I did spend time on accuracy and casting methods for heavy flies on long leaders, but not enough (not sure if there is such a thing as enough!) In the end, I didn’t use rolls or Speys, the mends were something I could really have done with, but there is a limit to what you can learn without real moving water. I didn’t practice enough with actual heavy flies casting into strong winds. Hard to do when the wind doesn’t oblige, but that was pretty much all I did on my guided days; single and double tungsten bead nymphs, as droppers or with indicators, on leaders between 14 and 20 feet long. They were a challenge on 14 feet, and on 20 feet I spent more time in tangles than I did fishing. My line handling was pretty bad, at least I thought so. My guides were both encouraging, but my lack of practice showed.
Both guides said they had enough tackle that I could have come with nothing at all and it would not have been a problem. That many clients were fitting in a day fishing with other family activities and couldn't justify packing a lot of their own tackle. Guide-loan gear was all rather high end. Both would have had me using a Sage One if I had not brought my own rod.
All fishing was with floating lines. I packed a couple of sinkers, but would have been better not to bother. If you are taking flies...size 14-10, black tungsten bead hare's ear/pheasant tail type things tied sparse and 14-10 parachute Adams, black gnat and goddard caddis...that was was was on my line most of the time! I took a lot of flies that didn't get used. All my old UK still water flies stayed in the box and only the newest ties, put together after I started reading what is used in NZ, were used.
Gear disinfection (anti invasive algae measures).
Its not a problem to find soap in supermarkets that you can spray on gear, but it is a challenge to find or carry means to soak things like boots. Don’t do as I did and use a prized water bladder to apply strong disinfectant, I don’t think my Dromlite will ever be free of the taste of Detol! (actually, it is now, but it took over a year!)
Bio-security at point of entry.
Transferring through Auckland I was very nearly late for my plane. 1.5 hours was not enough time to run 10 minutes late on landing, get through immigration, have my gear inspected by Bio-security, drop my bag and walk the 10-15 minutes to the domestic terminal. I managed, but it was all but at a run and arrived just in time to join the end of the line boarding my onwards flight! Despite my nest ground sheet being new, my tent having no floor and my boots having been scrubbed to out-of-box cleanliness, all were unpacked, taken away and the boots sprayed by staff.
Hope some of that ramble is useful for someone else's planning! Happy Travels!!
