Hi Dylan (just found your post on the introductions thread). I'm a kiwi too, it's good to find another here.
I'm suprised you don't find NZ a good place to rewild. To me it seems like theres enough wild space here, like the west coast of the south island for instance.
Where are you exactly? I'm in Christchurch. I'm lucky enough to live with a good friend whose also into rewilding. Unfortunately we've done more talking then action at this stage but we have done a few things such as catching/cooking eels, making an eel trap, looking for edible plants and attempting to make/use a bow drill (hope to get that working soon). We're hoping to be more active this summer.
Anyhow, I'm sorry to hear you're heading offshore soon but I wish you the best of luck with those bears. If circumstances change and you end up staying in NZ and you're near Christchurch, feel free to look me up.
I'd be keen to meet up with other rewilders, whether it'd be just to hang out or put ideas into practise.
