Doctors preparing for their second strike are refusing to accept a pay cut in exchange for less demanding rosters.
Of more than 3400 junior or resident doctors who will walk off the job for the second time on November 23, more than 80 work at Whangarei Hospital.
The doctors went on strike on October 18 and 19, as they have been unable to agree with the country's 20 District Health Boards over rostering practices. The dispute is ongoing, prompting the second strike.
About 120 Whangarei patients were affected by the first strike, with the number of people turning to the emergency department also down during the two-day action.
Twenty-one operations were delayed and 99 adult and 22 paediatric outpatients' appointments were rescheduled. The strike did not affect Northland's other hospitals.
