A Covid-19 vaccine could be produced in Australasia.

Australia is reportedly days away from locking in a deal for Oxford University's vaccine.

It's believed New Zealand might be able to access the vaccine through Australia.

Medicines New Zealand Chief Executive Graeme Jarvis says Australian companies are collaborating.

"There's a company called CSL, they manufacture influenza vaccines for global distribution, but they are also talking to some of the other companies about the potential to manufacture their vaccines as well."

He told Heather du Plessis-Allan we're part of the COVAX alliance.

"A whole lot of countries have pooled money together to look at getting around 2 billion doses by the end of 2021. 

"So it's not unexpected, but we just have to wait and see when the ink dries on the deal."
