Speaking to the Chronicle, Whanganui DHB acting chief executive Graham Dyer said over recent months the number of those unvaccinated has trended downwards.
"But my understanding is that some of that includes those on maternity leave and some who might not be here at the moment [and haven't had their vaccination status recorded]."
Dyer said he was comfortable with the DHB's position when it came to staff vaccination, and said he was confident there were plans to mitigate any staff losses as a result of vaccination refusals.
"By comparison, I think we're doing reasonably good compared to where some are."
Nationwide, roughly 95 per cent of the 80,000-strong health workforce have received at least one dose, with roughly 4000 so far unvaccinated.
The lowest first-dose vaccination levels were in the Bay of Plenty and the West Coast at 93 per cent, while the highest were in South Canterbury and the three Auckland DHBs at about 98 per cent.
