As eligible workplaces south of Auckland prepare to reopen on Wednesday, there's a push on for rules to be beefed up.
Given the high infectiousness of the Delta variant, Director-General of Health Ashley Bloomfield has advised Cabinet to tighten rules for workplaces operating under level 3.
Public health expert Michael Baker said we now know more about how the virus spreads and a rethink is essential across all levels.
"We know how this virus is transmitted but we need to revise our legal system to reflect that."
He spoke to Corin Dann.
