Amazon chief executive Jeff Bezos is rumoured to be in New Zealand after his private plane was spotted at Wellington Airport on Thursday.

His Gulfstream G650ER jet, which seats eight and cost an estimated US$65 million (NZ$102m), touched down in the windy city, but it's not yet been confirmed if the 56-year-old businessman was on board.

Bezos, who founded Amazon 25 years ago, has a stake in the company that is worth more than US$100 billion. His total net worth is an estimated US$130 billion.

The Wellington Airport spokeswoman was not immediately aware of a plane matching Bezos' description landing on the tarmac, but would check with operational staff.

The jet was managed by ExecuJet, the Wellington Airport spokeswoman said.

When contacted, an ExecuJet spokesman said he had "no idea" about Bezos possibly being in the capital, and had no other comment to make on the matter.

"I don't comment to the media about my business," he said.
