Corrections is recruiting 21 new staff for Ngawha Prison to cope with an increase in prisoner numbers from April.
A rising prison population nationally has led to 80 extra double bunker beds being added to Ngawha Prison, boosting its capacity to 628.
The new beds will be available from April.
Nationally, Corrections is looking to fill 600 new prison jobs by September - of which 100 will be recruited from overseas with experience in custodial, security, defence or police backgrounds to ensure a blend of experienced staff alongside new recruits.
Due to the large number of recruits being sought, Corrections was also advertising in Australia and the UK.
