People in the Bay of Plenty have got their two shots for summer - the region has reached its 90 per cent fully vaccinated target today.

Ministry of Health data shows 90 per cent of eligible people in the Bay of Plenty DHB area have had two doses of the Covid-19 vaccine.

Bay of Plenty is the 14th DHB to reach the target with six others not there yet.

Northland, Lakes, Tairawhiti, Taranaki, Whanganui, and West Coast DHBs are yet to reach 90 per cent fully vaccinated.

A Ministry of Health spokesperson says while it is great the Bay of Plenty has joined other regions with a 90 per cent fully vaccinated population, it is not an end goal for the Covid-19 vaccination programme.

"It is important that all regions reach this milestone and that as many people as possible throughout Aotearoa become fully vaccinated to better protect our communities from all variants of Covid-19."

Everyone who has had their second dose more than six months ago is eligible for a booster shot.

In December the Government announced it would be decreasing the gap between the second dose and booster to four months..

From January 5, people over the age of 18 who had their second dose at least 4 months ago can visit some walk-in sites for a booster dose.

From January 17, people will be able to book booster doses at BookMyVaccine.nz with an interval of four months from the second dose.
