It isn't clear if any staff at Whanganui Prison have been placed on 'special leave' after the deadline for them to be vaccinated passed over the weekend.
The Government required all prison staff around New Zealand to have their first Covid-19 vaccination by November 6.
The Department of Corrections said 202 prison-based staff across 18 prisons around New Zealand had not received their vaccination.
However, Corrections could not confirm how many, if any, are from Whanganui Prison.
A Corrections spokesperson told the Chronicle that by 11.59pm on November 6, 96.8 per cent of prison-based staff in New Zealand had received at least one dose, with 86.86 per cent fully vaccinated.
