Disgruntled health workers plan to continue strike action in the New Year as negotiations with district health boards fell through.
Several hundred staff walked off the job for a couple of hours last month in Auckland, Waitemata and Counties Manukau.
The action was in protest of what was described as an "over-stretched workforce" that's putting the patients at risk. The DHBs claimed the allied workers union had not signalled an issue.
Discussions after have failed to reach an agreement.
According to a Public Service Association spokesman 97 per cent of its workers, which included social workers, physiotherapists and occupational therapists, have rejected a new contract proposed by the DHB.
The union, which represents around 3000 health workers, said strike action would be escalated if an improved offer wasn't made by February.
The DHBs are being sought for comment on the details of the offer.
