In Australia, a New Zealand doctor is dealing with as many as a hundred covid cases a day at the epicentre of the massive Melbourne outbreak. Former Wellingtonian Megan Robb is the director of emergency at Melbourne's northern hospital - one of hundreds of Kiwis working in Victoria's hospitals. She says it's been mentally draining for health teams dealing with a second wave of covid. However, she told health correspondent Rowan Quinn, a strong team with a good sense of humour is getting them through.
