She said it was also saddening that these health workers were still not being recognised for the work they did for communities and have continued to do despite the insurmountable pressures and moral conflicts they faced daily.
"We hold out hope that mediation today will generate an offer we can accept but NZNO members are feeling exasperated and are willing to show the ministry and DHBs that we will continue to advocate and fight for the health and safety of our staff and communities without hesitation."
Hawke's Bay DHB chief executive Kevin Snee said the strike action would occur at every location where the DHB provided healthcare or hospital care services, but that contingency planning was already well under way.
This included seeking help from people who could volunteer to help cover essential work, although not life preserving, especially after hours.
Volunteers would be provided with support and training.
"This will be a very difficult time for everyone, and we thank everyone who has already offered assistance or who is considering helping," Dr Snee said.
The DHB was working with NZNO to ensure life-preserving services were available.
"Our aim is to keep everyone safe during the strike, patients and staff alike – and that will mean a significant change to normal services."
People should not delay seeking medical treatment or going to hospital if the matter was urgent, he advised.
People should dial 111 for emergencies or an ambulance, or could visit their GP, medical centre, local pharmacy or call HealthLine 0800 611 116.
Anyone who wanted to offer clinical or non-clinical volunteer support could call 0800 248 794 or email volunteers2018@hawkesbaydhb.govt.nz
