Vaccination isn't an alternative to an already infected hive. The vaccine was the first in the world and was only approved for the first time last year. That's not a feasible alternative at this time. The heat treatment they talk about is performed in the US too. You generally still need to burn your frames. You are allowed to char the inside of your hive body. It's not a meaningful difference as the frames are the more valuable part. It wouldn't surprise me if New Zealand allows charring the inside of the hive bodies and the farm decided against it due to labor concerns with the volume of equipment.
