If the person has had a dose of COVID-19 vaccine overseas

If you were partially vaccinated overseas with one dose of Comirnaty (Pfizer/BioNTech) vaccine, you will need to have another dose 6 weeks after your previous dose (or at least 3 weeks if you are at high risk of exposure to individuals with COVID-19). There is no maximum time limit between doses, so you do not need to repeat the first dose or receive a third dose.

Although, different COVID-19 vaccines are not interchangeable, it is recommended that if you have received one dose of any two-dose COVID-19 vaccine (including Vaxzevria/Covishield/AstraZeneca, or Spikevax/Moderna) outside of New Zealand that you have one dose of Comirnaty (Pfizer/BioNTech) at least 4 weeks after the first vaccine dose.

If you received one dose of COVID-19 Vaccine Janssen, you are considered fully immunised. However, in certain groups (such as border workers) at high risk of exposure to people infected with COVID-19 virus, may be advised to have a further dose of the Pfizer vaccine at least 4 weeks later.
