There is a feeling of complacency in the community. Not many people use the contact tracing app. And some stores do not cater for people who do not have the app. Passengers on public transport are supposed to wear masks but I regularly see Inter-City buses passing through Paeroa where passengers have removed their masks. As long as that continues, and the virus sneaks into the community because of "flaws" in the testing of border workers (airport, ports and quarantine facilities) we will get snap lock downs because our Prime Minister is overly cautious.
But we are one of the few countries where crowds are allowed into sporting venues - most of the time.
On a personal note my wife and I are annoyed at the travel restrictions as we want to see our family and grandchildren in Pakenham without having to pay heaps of money on our return to NZ to go into managed quarantine for 14 days.(Costs over $5,000).
