However, the DHBs believed the "crux of the issue" was largely to do with the issue of being paid double-time on weekends.
Currently the PSA members were paid double time for weekend work after midday on Saturday, whereas the majority of the 17 other DHB's employees nation-wide received only time and a half.
The DHBs had offered to protect the status quo for existing staff, so only new staff would be affected by the lower weekend rates.
Spokeswoman for the Auckland DHBs Julie Patterson was disappointed at the strike.
"Essentially the PSA is asking members to go on strike to seek a benefit for people who the DHBs don't currently employ that is out of step with PSA agreements for the rest of the country."
However the PSA claimed lower weekend rates would make it difficult for the DHBs to recruit and retain staff in an already lean workforce.
Just this weekend a Safe Staffing Healthy Workplace report in the Herald on Sunday highlighted frontline workers at ADHB were feeling the pinch of understaffing, high exhaustion and unpaid overtime.
Occupational therapist at Waitemata DHB, Laura Hunter, was one who felt that current workloads were unsustainable and risked early discharge of patients, inadequate follow-up, poor treatment success rates and life-long mental health and physical challenges.
"There's not enough time to do the job...we are constantly cutting corners and putting our clinical practice on the line."
She described fellow staff having lunch at their desks, no afternoon tea or lunch and doing up to 20 hours of overtime each week.
"They are working so hard to the detriment of their health and social life," she said. "People burn out there's a massive turnover."
