Most of the 55 midwives employed by the Northland District Health Board are among more than 1100 nationwide who have voted overwhelmingly to reject their pay offer and go on strike.
Eighty per cent of midwives' union Midwifery Employee Representation and Advisory Service (Meras) members employed by all 20 DHBs have cast their votes.
Of these, 90 per cent voted to reject the DHBs' offer and to take strike action.
Midwives have given notice of two-hour work stoppages every day on every shift over a two-week period - effective November 22 to December 5.
Deb Pittam, midwifery director and service manager at NDHB, said her staff were developing contingency plans to manage the significant disruption expected during the two hour-work stoppages.
