Wider testing at Lakes District Hospital in Queenstown after a second nurse tests positive for Covid-19

Seventy four staff who worked at the Queenstown hospital over the past two weeks are now being tested - after the first nurse tested positive on Sunday - followed by the latest case yesterday.

Callum Proctor says the second nurse was a close contact of first nurse - and has very mild symptoms.

Fifteen close contacts, including four patients are in self-isolation.
