The National Party says anyone who refuses a test on day three of their stay in a managed isolation facility should automatically be moved into quarantine. Currently it's only compulsory for testing on day 12, and the Government has said that's enough to keep the public safe. But National's health spokesperson Shane Reti says compulsory day three testing could prevent staff and others in managed isolation from catching the virus. It's one of five proposals put forward by the Opposition yesterday, which also include requiring people who test negative for Covid to be notified within 48 hours so they can get back to work sooner. Dr Reti also wants to improve the Covid tracer app, record the details of everyone who shows up for a test - even if it's denied - and re-test positive cases to get better genomic data. He told our reporter Matthew Theunissen he believes the five proposals could be implemented in just five days. He spoke to reporter Matthew Theunissen.
