About to go spend 60 days by myself in deep Fiordland (pic related)

My survival kit is basically:

>several drink bottles (lots of clean rivers/creaks)
>a shitty folding knife
>waterproof sleeping bag with cover thing (dunno if they have a name?). Area is wet as fuck
>a small gas cooker + lighter/matches
>PSE Madfish bow + arrows
>some rope, dunno why I'd need it tho
>some instant noodles/chocolate to last me a week in case I start starving
>camera+solarcharger for picture taking

Mainly going to be hunting fish since all our birds down here are protected. We also have deer/pigs which I'll go for if I run into any, got proper permits just in case.

Never been on /out/ desu but figured you guys would be worth asking for advice. Never gone innawoods before, only hiking via tramping huts. Anything I should add to my kit before I leave?
