Auckland doctors continue to be frustrated by problems with the supply of measles vaccines.
ProCare network clinical director Allan Moffitt said they had seen unprecedented demand from patients for the jab as the measles outbreak continues.
He said vaccine supplies had already been redistributed to clinics in high-risk areas that were running low or had run out, but much of that stock had now been used up.
Priority was being given to children who were due for their vaccinations or who had never been immunised, he said.
"We should still be able to vaccinate those people, we are trying to reserve enough vaccine for the next week to still maintain normal vaccine levels," Dr Moffitt said.
