Wellington Airport applies to extend runway

Wellington International Airport has lodged an application to extend its runway with Wellington City Council and Greater Wellington Regional Council.

The airport is seeking permission to build a 350-metre runway extension in a bid to attract long-haul flights from Asia and the US at a cost of $300 million. The airport's 66% controlling shareholder, Infratil, is pushing for central and local government funding to cover most of the capital costs, arguing the investment is in the national and regional interest while not being viable on a standalone commercial basis. Wellington City Council owns the remaining third.

In a media release, the airport's chief executive, Steve Sanderson, said public feedback on the proposed extension had been encouraging, and the airport had been working to overcome people's concerns.

"We have completely reviewed the construction traffic route, which will now involve significantly fewer truck movements per day and operate mostly through Airport Rd and Onepu Rd in Lyall Bay," Mr Sanderson said. "Further coastal assessments were conducted on the likely inshore effects of the proposed runway extension and the wave focusing structure, as well as the effects of sea level rise on the runway extension. We are pleased to advise that the inshore effects are expected to be within the existing seasonal variations that occur and the runway will be resilient to the effects of sea level rise."

Mr Sanderson said cost-benefit analysis showed a benefit-cost ratio to the country of 2.3 and a net benefit to investment ratio of 7.6.

The two councils will undertake completeness checks and determine whether any further information is required, Mr Sanderson said, with public notification and formal submissions requested in June. The airport is looking for its application to be heard in the Environment Court as soon as possible.

Airlines who would benefit from the extended runway would need a major hub in Asia or North America as the consents sought would enable direct long-haul services from Wellington to those destinations. Mr Sanderson said it was not surprising Air New Zealand and Qantas Airways have both said they wouldn't use the runway, as they don't have hubs in those locations, and the viability of the plan did not depend on their support.

The airport announced yesterday it was looking at selling up to $75 million of seven-year bonds. It is undertaking extensive upgrades, adding an eight-storey carpark building, improving its international arrivals area and building an on-site hotel as well as extending its terminal.
