There are two new measles cases in Northland.
It brings the total number in the region's outbreak to 12, with one unrelated case in Queenstown.
However, Health NZ said the two latest people were already in quarantine during their infectious period because they were close contacts of existing cases.
That meant there was no risk of them spreading measles to the community.
All other cases around the country, and their close contacts had, now finished their isolation periods.
The National Public Health Service clinical director of protection Susan Jack said health workers and the communities had worked hard.
"We're incredibly grateful to everyone who has worked with health services and stayed home to protect their communities. Your efforts have made a real difference," she said.
"We also acknowledge the thousands who have come forward so far to get vaccinated and thank our dedicated providers and kaimahi across the motu for supporting this important mahi."
Pop up vaccination clinics have been operating in both regions since the cases.
There had been particular concern in Northland because of the very low childhood vaccination rates. Mobile clinics were sent to rural places.
Jack said people in Northland, Queenstown and Cromwell should still be alert for measles symptoms and encouraged people to be vaccinated.
"Being fully immunised means you can carry on with confidence - even if you're identified as a close contact of a measles case, you won't need to quarantine," she said.
Measles is highly contagious and up to 90 percent of non-immune people (those who have not been vaccinated or have not already had it) will be infected if they are exposed to the virus.
About 80 percent of New Zealanders are immune - well below the 95 percent coverage needed to prevent an outbreak.
