Nurses in the upper North Island begin several local industrial action today

The Nurses Organisation says their concerns about staff shortages continue to go unaddressed - following a 24-hour nationwide strike last month.

North Shore District Nursing Service nurses will carry out a week long uniform strike - instead wearing t-shirts saying 'not enough nurses'.

Auckland Hospital's cardio-thoracic and vascular intensive care, and Whangarei Hospital's Acute Surgical Services nurses will undertake a redeployment strike.

They're usually sent to short-staffed areas when required - but instead they'll remain in their wards, only going for life preserving reasons.
