Whanganui, Ruapehu, South Taranaki (between Whanganui and the Pātea River) and Rangitīkei had active cases.
The ministry says its daily reported cases may differ slightly from those reported at a DHB or local public health unit level.
This is because of different reporting cut-off times and the assignment of cases between regions, for example when a case is tested outside their region of residence.
The DHB region is currently sitting at 90.3 per cent fully vaccinated against Covid-19 (ages 12 and above), with 74.1 per cent of those eligible receiving booster shots.
Out of a population of 6588, 206 children aged 5 to 11 have been fully vaccinated; 2635 are partially vaccinated.
