New Zealand has had more community cases of Covid-19 overnight -- but the Government won't say how many.

The whole country remains in a Level Four lockdown until at least Friday -- and Auckland will remain at Level Four until at least next Tuesday.

There are now more than 107 cases and more than 400 visits to locations of interest -- with a number of supermarkets, two schools and a few Auckland bus routes added to the list overnight.

But Covid-19 Response Minister Chris Hipkins told Mike Hosking there's no sign of community spread on the Coromandel Peninsula, so far.

"There will be more cases today, so unless there's something in the cases today, but as of last night it was looking reasonably encouraging."
