The South Waikato town of Tokoroa has confirmed at least one case of COVID-19.

In a post on Facebook, Mayor Jenny Shattock says there's one confirmed case and another probable case.

Earlier today Health Minister Chris Hipkins told Morning Report there are more COVID-19 cases related to the Auckland cluster which will be revealed at 1pm today.

He says for New Zealand to move to alert level 4 there would need to be a number of clusters and unconnected cases.

The country will be told this evening if the Covid-19 lockdown measures to stamp out community infection will be extended past midnight.
