Six60 headlined a sellout concert to 25,000 people at Claudelands on sunday night . An MP has sown confusion by telling potentially tens of thousands of people to self-isolate after attending big events in Hamilton and Auckland on Saturday, despite the Ministry of Health offering no such advice. Māori party co-leader Rawiri Waititi told followers on social media that if they had attended either the Six60 concert in Hamilton or the Parker v Fa fight at Spark Arena that they were being asked to self-isolate on their return. Waititi said this would give authorities time to rule out these events as possible emerging hotspots .
