Deputy Prime Minister Grant Robertson is stepping in for his boss, as Jacinda Ardern takes her first sick day since the COVID-19 outbreak.
A spokesperson for the Prime Minister said on Tuesday she's "suffering the consequences of having a child that goes to daycare and has picked up the seasonal sniffle".
Ardern's 3-year-old daughter Neve also has the sniffles.
The spokesperson said Ardern will be working from Premier House in Wellington, the official Prime Minister's residence in the suburb of Thorndon, near Parliament.
Ardern will join meetings via Zoom, the spokesperson said, and Robertson will fill in for her during Question Time in Parliament, which is resuming after a three-week recess break.
Robertson will also fill in for Ardern during 'Caucus Run', a tradition of parliamentary sitting weeks where MPs stop for questions on their way to party caucus meeting rooms.
The spokesperson confirmed Ardern got a COVID-19 test on Tuesday morning, because anyone with symptoms of the virus is advised to by the Ministry of Health.
COVID-19 symptoms include sneezing and runny nose, a new or worsening cough, a sore throat, fever, shortness of breath, temporary loss of smell, and altered sense of taste.
Ardern has received two doses of the COVID-19 Pfizer vaccine.
