Students at Māngere College took one for the team of five million, getting a jab in the arm for another deadly disease the country's had a brush with - measles.
Many of them are part of a missing group of half a million New Zealanders, aged 15 to 30, who may not have been fully immunised.
That gap allowed measles to take hold last year infecting more than 2000 people and then jumping the pacific to Samoa where it became deadly.
Today the government launched a campaign to track down and vaccinate the people who hold the key to keeping it out in future.
Health correspondent Rowan Quinn and videographer Simon Rogers were at the launch.
