More than 300 Bay of Plenty District Health Board workers have voted to take strike action in a dispute over pay.
The health workers have rejected an offer of a 0.7 per cent pay rise, labelling it "insulting".
In total, 12,000 health workers nationally including 374 in the Bay will take part in the strike action which begins on August 25, with a work to rule policy, followed by an overtime ban, and two days of strike action.
Striking workers include mental and public health nurses, occupational therapists, physiotherapists, anaesthetic technicians, dental therapists and administrative staff, among others.
PSA national secretary Richard Wagstaff said the 87.1 per cent vote to strike showed the seriousness of the funding crisis in the health sector. It would be the biggest industrial action in a decade, he said.
