The Corrections Department said it brought in guards from other prisons because of "a higher than usual number of staff calling in sick", Stuff reported.
Corrections Association president Alan Whitley said at least 30 staff members from Paremoremo prison called in sick on Sunday.
On Saturday a Corrections staff member was assaulted, Stuff reported.
Department of Corrections Regional Commissioner Jeanette Burns said she was at the prison on Sunday and it was operating as usual.
Over the last fortnight there has been an increase in organised violence toward staff, orchestrated by gang members at the prison," Burns said to Stuff.
On Friday a maximum security prisoner with gang affiliations attacked a Corrections Officer at the Auckland prison.
Burns said a staff member was giving the prisoner a mop and bucket to clean his cell when he punched the officer in the face without warning.
"Other staff reacted immediately to bring the incident under control, with the use of pepper spray, and the staff member was taken to hospital for medical assessment."
Last week there had been three staff assault incidents at the prison, she said.
"Last Friday, two staff were assaulted by a prisoner who was attempting to make an illegal phone call.
Auckland Prison contains New Zealand's only specialist maximum-security prison unit.
