The investor plus category requires applicants to invest at least $10 million in New Zealand over three years.
INZ said the application included the necessary documentation and was assessed as meeting immigration requirements.
No investments were detailed, but a Page-backed company is bankrolling the Wisk pilot-less air taxi, currently being developed at a site near Christchurch.
Page arrived in Auckland with his child in January after the Ministry of Health approved a request for a medevac flight.
Health Minister Andrew Little confirmed in Parliament earlier this week the application met all the necessary requirements.
The day after the application was received, a New Zealand air ambulance headed to Fiji.
On arrival, Page and his child were taken to an isolation area in the hospital.
