Alert level 2 has been extended to 11.59pm on Tuesday in Wellington with the government calling for people to use extra caution.
This follows a positive test result by the partner of the Australian case who visited the capital last weekend.
Covid Response Minister Chris Hipkins, who made the announcement Sunday afternoon, said the government had been advised by New South Wales health officials that the man's partner was not considered infectious while in Wellington but may have been infected toward the end of their stay.
Minister Hipkins said the government would not rule out extending alert level 2 further in the interests of safeguarding the community.
“Progress has been good, and no community cases have been found. Repeated wastewater testing has also not detected any Covid-19 in Wellington, Porirua and the Hutt Valley.”
