Whanganui is on high alert after the appearance of its first Covid-19 case from the Delta outbreak. Two locations of interest have been identified so far - the public toilets at Kai Iwi Beach on Tuesday, and the Polson St Foodmarket on Friday. Health authorities says the person is well and self-isolating at a supervised isolation unit. They'd recently travelled outside the region. Whanganui District Mayor Hamish McDoull spoke to Corin Dann.
