Covid-19 modeller Shaun Hendy says it's important to discuss the potential of severe health consequences if restrictions are lifted.
New modelling data shows if just 80 percent of the country's over fives are vaccinated, 7000 people could die from the virus every year.
That modelling, by Professor Hendy and others, has been criticised by another analyst Rodney Jones, who says scaring people won't encourage them to get vaccinated.
But Professor Hendy stands by it, and told Morning Report people have been talking about opening up once the country hits a vaccination rate of 80 percent and the consequences of that should be explored.
