There's concern New Zealand's assess to vaccines will be threatened by production issues.

AstraZeneca and Pfizer both say production problems mean they can't supply expected numbers.

And the EU's now warning it could restrict exports of vaccines made in the region as a result.

Royal College of GP's Bryan Betty told Heather du Plessis-Allan it's important to know we definitely have a vaccine supply on its way.

"The Government needs to do what it has to do. I know we have our agencies talking directly to the supplies about cost and contracts. Those discussions need to go, and we need to do what we can."
