In November last year, there were 900 unvaccinated police staff.
Fire and Emergency said it was confident it would be able to continue to respond and keep communities safe.
About 80 per cent of the more than 10,000 firefighting staff in New Zealand are volunteers.
Last year Fire and Emergency tweeted that they would be responding to emergencies in all Covid-19 protection levels.
It said their staff on callouts would wear face coverings and practise physical distancing where possible.
