Sorry - that sounds horrible, what island were you on that snows during Easter? Also, always assume some asshole burnt down the hut. Apart from that being a semi-regular occurrence now, it also just .. happens. Assholes book and stay at DoC cabins too. Also lots of drinking and illegal bonfires.
For anyone else who's worried about making a similar trip, please use this govt-made website which talks about what's recommended, as well as has an online service for logging your walks. If there isn't anybody to tell that you're going on one of these hikes, that means you shouldn't go. It isn't optional.
For anyone in other countries without this service - if you're backpacking in hostels, or have a booking at a hotel after - ring and tell the staff before you go. If it's through AirBnB.. Well, I hope you make friends with someone who can check in with you before you leave!
