A staff member at Cape Kidnappers golf club said a large group of visitors played the course and stayed at the facility's luxury lodge on the nights in question - but he was unaware how they had arrived in Hawke's Bay.
The Boeing's presence at the airport sparked questions on social media about why Hawke's Bay did not host international commercial flights, given it was capable of accommodating a plane that could be configured to carry up to 149 passengers.
Commercial transtasman flights into and out of Hawke's Bay Airport were ruled out last year after a study found they were not financially viable.
The study backed up previous research showing carriers were not interested in running international services from the Bay because they did not believe they would generate sufficient passenger demand.
The closest the region will come to welcoming a commercial international flight in the foreseeable future could be July's one-off McLean Park NRL match between the Melbourne Storm and Sydney's St George Illawarra Dragons.
Mr Dalton said yesterday negotiations were ongoing over the possibility of bringing a charter flight of Storm fans direct from Melbourne to Hawke's Bay.
But while larger planes are able to fly into the Bay, the short runway restricts them from flying out again with a full complement of passengers and full fuel tanks. The solution for Storm fans would be to take on enough fuel for a stop-off in Auckland before refuelling there for the trip to Australia.
