New Zealand faces an "unacceptably high" risk of as many as nearly three border breaches each month - and by some measures the country is more threatened than Australia.
That's according to a new analysis by public health researchers on both sides of the Tasman, who warn that risk of new Covid-19 incursions is growing even with vaccinations and call for urgent improvements.
The researchers looked at nine border failures in New Zealand, including the August Auckland cluster that resulted in around 180 cases and three deaths, and seven in Australia - six of which led to lockdowns.
Canterbury University modeller Michael Plank told Mike Hosking we might have had more cases at the border - but Australia's had six lockdowns.
He says we've also had fewer cases that have led to community transmission than them.
Australia's had no cases of the virus passing from one new arrival in MIQ to another - unlike us.
