Ski fields just this week said they were seeing the busiest time for the school holiday season: https://www.odt.co.nz/regions/queenstown/holiday-boost-skifields
I think this was to be expected. Kiwi families have a bit of cash in the discretionary spend bucket due to having been locked down, so are now spending it. It is well-known that school holidays are the busiest time on the skifields, so you would expect Aussies to avoid that if at all possible. So it's no surprise that the scarcity of Aussies hasn't impacted the skifields much.
My issue is that folks such as @handle9 said we needed to open for the economy and the approach the government has is not sustainable.
Oddly enough they haven’t responded to the facts I brought to the argument.
