I worked at a cat boarding kennel here in Canada. We had one cat going to NZ - and he was able to spend his quarantine with us, and then fly out.

Couldn't be in touch with other cats, but we only let one cat family out at a time, so NP. And the quarantine was only 4 months.

Ask your vet for some places to call. Maybe they can be quaratined with a friend?

good luck!
