The Nurses Organisation is being taken to court over their latest announced strike action.

Nurses will strike for eight hours on Thursday the 19th of August.

MIQ and border workers will not strike and they say there will still be life preserving staff levels in all hospitals.

But the DHBs say that isn't good enough and the levels that are needed aren't being promised, so they are off to the employment court.

Spokesperson for the DHBs Jim Green told Mike Hosking say they want to be sure the staff level requirements are met.

“We think it really does need to be certain about this, it’s very important for the safety of the public, so that’s why we’re going to the court.”
