Pharmacists and the Opposition are calling for the Government to urgently let chemists give out measles vaccines to help slow a growing outbreak.
Authorities are trying to contain the spread of the highly contagious disease, with 937 cases reported nationwide by the weekend and 759 in Auckland alone.
There are 864 pharmacists around the country who are allowed to provide vaccinations for the flu, shingles, whooping cough and meningitis, but current rules mean they don't get funded to provide the MMR (measles, mumps, rubella) vaccine.
National Party associate health spokesman Shane Reti says the Ministry of Health needs to use every option it has available to stop the outbreak and should change the regulations urgently.
"We shouldn't let its reimbursement policy get in the way of vaccinating children," he said.
