Notice for a second 24 hour strike from 7am on 12 July is anticpated next week.
Acting Chief Executive Officer Neil Wanden said MidCentral, like all New Zealand DHBs, will be rescheduling all non-urgent hospital services in preparation for industrial action.
The DHB was working with NZNO to ensure emergency and life preserving services were available in the event of industrial action going ahead, he said.
Mr Wanden said the staff covered by the NZNO MECA are a highly valued part of the MidCentral team and he respected their right to take such action.
However, he was concerned about the impact that industrial action would have on patients and staff.
Patients scheduled for surgery or other appointments would be contacted if they were going to be affected by changes to services.
During the disruption, the main priority for MidCentral would be ensuring patient safety. A contingency planning team is working hard to make sure emergency and life preserving services were available during any industrial action, he said.
Mr Wanden said it was important for people to still seek medical treatment, if required, during the industrial action.
Free medical advice is available 24/7 through Healthline (phone 0800 Healthline -0800 611 116) and people could also visit their GP or a local pharmacy.
If the matter is urgent people should come to the Palmerston North Hospital, and dial 111 for an ambulance in an emergency.
Information about changes to services would be provided on the MidCentral DHB website and anyone with questions about how the industrial action might affect themselves, or their family and whānau, is encouraged to call the Hospital toll-free on 0508 MidCentral (0508 643 236).
