Another expansion plan for the airport, half owned by the Government and half by Napier City Council and Hastings District Council, is a 20ha business park, with the first section of the access road to be built before June 2012.
Stage one will provide 4ha of commercial development, with 16ha more planned together with a new access from Watchman Rd.
He said the airport is not selling the land.
"We are looking at several options including leasing land, leasing buildings, design and build or design, build and operate."
The airport has some reserve funds to kickstart the development, he said.
"We have not built much for a long time, apart from the runway extension."
The rental car companies had agreed to shift to the business park once the first section of new road was complete, between the airport carpark and the highway.
"This will free up space in the terminal for other clients," he said.
Mr Wootton said he is the airport company's first fulltime employee - the general manager works part-time.
