Medical practices in Northland without the measles vaccine will have to wait next week and prioritise children 2 years and under, the Ministry of Health says.
Unprecedented demand for the MMR vaccine throughout New Zealand had led to a shortage and forced GPs in Northland to reschedule bookings for those wanting to be vaccinated.
A shipment of 52,000 vaccines is due in New Zealand this weekend and will be distributed where needed, including GP clinics throughout Northland, from next week.
The number of confirmed measles cases in Northland stood at 40 as of Wednesday and a further seven cases are under investigation.
An epidemic has been declared in Auckland where 959 cases have been confirmed of the more than 1000 throughout New Zealand.
