Junior doctors employed by district health boards have announced they will strike for a second two-day period this month.
The NZ Resident Doctors' Association (NZRA) has this afternoon released plans to strike between January 29 and 30.
It comes a day after the group confirmed that a 48-hour period strike would take place next week starting at 7am on Tuesday until 7am on Thursday; after mediation with DHBs failed to come up with anything they agreed on.
The association claims DHBs are pursuing claw backs in terms and provisions of the Multi-Employer Collective Agreement.
NZRA said the DHB team's claw backs would remove the protection of the union and expose vulnerable junior doctors to disruptive and dangerous work conditions.
The association's senior advocate, David Munro, said: "The [residential medical officers] are more determined than ever not to accept claw backs to their terms and conditions.
"This vote for a second strike testifies to their resolve. The RMOs are clearly not going to be backing down.''
NZRA president, Dr Courtney Brown, said the DHB group's position meant junior doctors could be moved to any hospital in the country as district health boards see fit.
"RMOs could be required to work for more than 16 hours in a row - without guarantee of rest or safety,'' she said.
"RMOs could lose access to education and training, jeopardising the quality of care we are able to deliver to our patients and a whole lot more.''
