There are now two confirmed cases of Covid-19 within Whanganui District Council's boundaries, with a household contact of Saturday's case also testing positive.
Sunday's case was isolating previously, so there are no new locations of interest at this stage.
The case was first reported yesterday in Waikato's figures, as they were recorded as having a Waikato address.
Whanganui District Health Board chief executive Russell Simpson said he expected Whanganui to mirror other parts of the country, with cases migrating around New Zealand as people travelled.
The DHB had been prepared for cases for "quite some time, both in the community and in hospital", Simpson said.
