Some lovely photos, and you certainly chose some good rivers for rafting.
I fish in NZ each Jan, and last year took a packraft as a means of getting downstream at the end of the days fishing, and it was a real hoot, except for an involuntary swim early on in the trip when I side swiped a large boulder and tipped out. We fished the Glaisnock and Worsley rivers in Fiordland, and although not the most exciting rafting prospects, were fun enough, particularly the Glaisnock after some heavy rain.
Am off into one of the Karamea tributaries next Jan, where I’ve fished a few times, and very much looking forward to rafting it - have previously liloed bits of it, but it was very cold!
Packrafts seem unknown in Australia - when I purchased mine, neither the chap who imports most of the rafts to Melbourne, nor one of our main kayaking shops had heard of them.
The kiwis have pretty perfect rivers for packrafting, so I imagine it is more likely to catch on over there - there was an article I heard of in one of the NZ mags about a chap packrafting the d’Urville R in Nelson Lakes Nat Park, but that’s really all I came across.
