Hon Dr AYESHA VERRALL: From today, businesses and organisations can register online as a critical service if they think they will meet the criteria when we enter phase 2 of our Omicron response. Critical services include food production and its supply chain, key public services like health and emergency services, lifeline utilities such as power and water supplies, transport, critical financial services, news media, and social welfare. It also includes human and animal health and welfare. Businesses will self-assess to take part in the scheme and will need to declare that they meet the relevant criteria. In doing so, there needs to be an awareness that bringing close contacts into the workplace will come with risks, as rapid antigen testing sensitivity can range from 80 to 95 percent accurate, meaning it can miss some cases.
