A case reported yesterday in a recent returnee in managed isolation had been reclassified as not a case, it said.
The country's total number of active cases is 25 and the total to date is 2302.
The ministry announced on Sunday two weak positive Covid-19 results had been detected in Wellington's wastewater.
It said it was likely this was due to recently recovered cases continuing to shed the virus.

Yesterday, one new case was detected in managed isolation.
It also confirmed a mariner who had tested positive for the virus had a historical infection.
