Jacinda Ardern says she's aiming for 100,000 or more Covid-19 vaccine doses to be administered on Super Saturday.
The Prime Minister wants to beat the previous record of 93,000 doses in a day.
Ardern will be visiting vaccination centres in Porirua, the Hutt and appearing on the Vaxathon.
Super Saturday Vaxathon will be on TVNZ2 from noon to 7pm that day.
"We're all working very hard but it can't stop on Saturday," she told Breakfast on Friday.
Ahead of the event, Ardern said she was heading to Taranaki to remind people that Covid-19 and the vaccination programme wasn't just for those in Tāmaki Makaurau/Auckland.
"We need everyone in every corner of New Zealand to be protected because as you can see Delta has a way of moving through unvaccinated people wherever they are in the country," she said.
So far, 83 per cent, of the eligible population have had at least one dose of the vaccine.
The Government has a target of more than 90 per cent, which Ardern said would be about 75 per cent of the total population.
Out in the regions, the PM said she'd been talking to teams working on the vaccine campaign on the ground, as well as playing the role of distracting those who have a needle phobia.
"If you've had that first dose and it's been three weeks, go and get your second on Saturday, if you haven't been vaccinated at all, come down, ask your questions, there are medical professionals there and people from your community that will be able to talk to you about the vaccine," Ardern urged.
"And if you're already vaccinated, find someone who isn't - one of your family or friends - and talk to them and encourage them.
"Everyone has a job this Super Saturday ... please everyone, do it for yourself, but do it for your community."
