The Government remains confident of Auckland's chances of stamping out its current outbreak of Covid-19.

Auckland recorded another 18 new community cases yesterday and five cases from the past fortnight are yet to be epidemiologically linked to existing cases.

Experts are concerned about the number of cases that have been infectious in the community and the coming days will be crucial to bringing the outbreak under control.

But Deputy Prime Minister Grant Robertson told Mike Hosking the current case numbers are in line with expectations.

“The kind of numbers that you’re seeing at the moment aren’t the exponential growth numbers, they’re the rumbling along of unfortunately, infections within households largely or occasionally across a couple of households. That’s unfortunately part of Delta.”
