The situation the country has found itself in was "déjà vu" after the second lockdown in less than a month, one medical professor says.
The latest cases of Covid-19 have plunged Auckland back into Level 3 lockdown, with the rest of the country at Level 2 - coming barely two weeks after the last three day lockdown.
Auckland University professor of medicine Des Gorman told Mike Hosking it seemed plans were being made up on the spot.
He said it showed our "inconsistent risk-management approach", and the Government needs to improve
"If we needed to be in level three two weeks ago, then coming down to level two in one was clearly precipitous and early."
Gorman said the Government's Covid-19 response was too much politics and not enough science.
He was particularly critical of the contact tracing system, which he said hadn't advanced much from a year ago.
Phoning someone and when you get no answer simply calling again was "profoundly inadequate".
He said contract tracing teams should be visiting homes to track someone down at that point.
Gorman was also unsure of public health messaging, querying what the 21-year-old Covid-19 case who went to the gym after getting a virus test was told by his GP.
