Fifteen people in Wellington have received expired Covid-19 vaccines and six people in the Bay of Plenty have received low doses.
The incidents have been reported by Covid-19 Vaccination and Immunisation Programme national director Jo Gibbs, and no-one has been harmed by receiving the expired doses, which were given 24 hours after the vaccine had expired.
In a statement, the Ministry of Health (MOH) said Capital & Coast District Health Board had contacted the affected people and was encouraging them to get vaccinated again.
