The National Party's Covid-19 spokesperson Chris Bishop says if the national vaccine booking system isn't up and running soon it could put the whole rollout at risk.
The Government has laid out a timeline of when the wider population can expect to receive their vaccine - with under 35s being the last to be vaccinated from October.
The Prime Minister Jacinda Ardern says the vaccination programme is ahead of plan, with nearly one million doses administered.
But the National Party's Covid-19 response spokesperson Chris Bishop told political reporter Charlie Dreaver the government's plan is a poor one.
