Google co-founder Larry Page travelled to New Zealand to get hospital treatment for his young child despite the country's borders being closed.

The billionaire does not have New Zealand citizenship, but according to multiple reports is spending the Covid-19 pandemic on an island in Fiji.

The Warehouse founder Sir Stephen Tindall, who has met Page on a number of occasions, confirmed to Stuff that he came to New Zealand "quite a while ago" because his young child needed hospital treatment in Auckland.

It is understood Page has since left the country after his child received treatment from Starship, according to Stuff.

In a statement to Stuff, Immigration NZ border and visa operations general manager Nicola Hogg confirmed Page met relevant requirements to be approved entry to New Zealand.

The details of what those requirements were have not been provided.

Page, 48, founded Google with Sergey Brin in 1998 and is the sixth-richest person in the world and worth US$121b (NZ$171b), according to Bloomberg. The company owns Google, Gmail and YouTube.

Google's parent company Alphabet has reported large growth during the pandemic which it put down to an increase on online advertising due to more customers shopping online.

Prime Minister Jacinda Ardern says she wasn't aware that Google billionaire Larry Page had been allowed into New Zealand for medical reasons.

"Nor would I be," she told reporters this morning. 

"We have roughly in any given year roughly 100 medivacs into New Zealand. The decision for a patient to be part of a medivac is made by clinicians.

"I'm not advised of every single individual ... at any given time because politicians do not make those decisions, nor should they."

Asked if she was comfortable with the decision, Ardern said: "I absolutely trust our clinicians to make decisions between those in the host country and receiving country around what is best for a patient.

It happens for all sorts of people for all sorts of reasons.

"She said she wasn't sure if she should have been briefed if the sixth richest man in the world was seeking to come to New Zealand.

"I don't think it's necessarily important for me to know the private medical details of someone, a family member, or their family situation."
