Christchurch Hospital nurses say their safety is being put at risk while Te Whatu Ora weighs up building some much needed parking for them. A shortage of parks at the hospital has seen nurses assaulted, stalked or getting their cars vandalised in recent years. The Nurses Organisation said staff were arriving well ahead of their shift to find a park, sometimes streets away from the hospital and nurse shortages were compounding the problem, a Christchurch Hospital delegate said in a statement.
