Anaesthetic technicians at Rotorua Hospital will strike for five days this month, after a breakdown in talks with the Lakes District Health Board over their pay and working conditions.
The Anaesthetic Technicians' Union, Apex, says the board had also withdrawn support for adequate rest breaks between certain shifts.
A Union spokesperson, Luke Coxon, says the technicians wanted a pay rise of 15 percent, but were offered a 6 percent initial increase, rising to 17 percent over time.
He says they were at breaking point.
The strike means any elective surgery in Rotorua between February 18-22 will be delayed.
