National Party leader Christopher Luxon has tested positive for COVID-19 on Monday.
A spokesperson for his party told Newshub he is now isolating in his apartment in Wellington.
The news comes just hours after he fronted a press conference at Parliament on Monday evening to respond to the Government's reprioritisation policies.
Luxon also attended the Wānaka A&P Show on Saturday, before heading to Auckland's Big Gay Out on Sunday along with his deputy Nicola Willis and multiple National MPs.
It's the second time Luxon has tested positive for COVID-19, with a previous infection in 2022.
Other politicians who have previously tested positive for COVID-19 include current Prime Minister Chris Hipkins, Mt Albert MP Jacinda Ardern, Finance Minister Grant Robertson and Attorney-General David Parker.
Earlier on Monday the Ministry of Health revealed there have been 11,544 new cases of COVID-19 reported in New Zealand over the past week.
There have also been a further 12 deaths attributed to the virus.
University of Otago epidemiologist Michael Baker told RNZ that New Zealand can expect a "succession of pandemic waves" in the future.
"These are going to be driven by things that are hard to predict - particularly new, emerging subtypes. In addition, we've got waning immunity and also changes in behaviour … we have other COVID subvariants on the horizon that might drive further waves.
"I would say it's safe to predict that the pattern we've seen in the last year is what we can expect in coming months, unless there's some huge shift in our ability to manage this pandemic."
