The pay row between radiographers and their employers has deepened, with a second group in Auckland issuing a strike notice.
The radiographers, who carry out X-rays, images and scans, say they will continue strike action until the dispute is settled.
On Monday, Counties Manukau DHB suspended four radiographers, sparking the announcement of a nationwide day-long strike on 7 September.
Workers reacted to the suspension of another three union members on Tuesday by telling the Auckland District Health Board they will strike for three days at Auckland City Hospital from 3 September.
Radiographers will also walk off the job in Counties-Manukau for four days from Thursday.
For their part, district health boards say it is up to radiographers to respond to a revised pay offer made two weeks ago.
Auckland and Counties-Manukau DHBs have now suspended seven striking radiographers and say they cannot continue to pay staff for work that is not being done.
Counties-Manukau DHB says if possible, people should visit their family doctor rather than going to Middlemore Hospital in Auckland during the strike.
The radiographers' union, the Association of Professionals and Executive Employees, says the suspensions have outraged workers and increased their frustration.
