You can't suddenly change the terms of employment for a large group of people, especially when they're largely from one voting bloc.

I get that employees are typically considered trash who have to accept whatever might be thrust upon them should they want to keep their jobs. But employee protections do yet survive and carry weight in New Zealand.

Given the relative success so far, any option involving mandatory testing of workers would be far messier, involving contentious legislation.
