Whanganui-based Registered nurse and NZNO National Delegate Carmel Scott said the move to strike is a result of nurse's pay packets just not keeping up with the cost of living.
"It's the cost of living, and it doesn't attract people. Who are you attracting to a career that doesn't meet the standard needs of living?
"People are looking overseas and looking at other opportunities. We want to keep nurses here."
In Whanganui, a number of surgeries and outpatient services will affected as a result of the strike, but the strike hasn't affected the oncology unit or existing Covid-19 vaccination appointments.
The DHB has been asked how many services or appointments have been affected.
On Tuesday Prime Minister Jacinda Ardern said that while the government was committed to lifting wages, what was being demanded was not realistic.
"The nurses' expectation, or at least the ask, had been for a 17 per cent increase - we're just not in the position to be able to deliver that."
