length of in the early 1970s, to handle Douglas DC-8s. Wellington's original domestic terminal was built as a temporary measure inside a corrugated iron hangar, originally used to assemble de Havilland aircraft. It was known for being overcrowded, leaky and draughty. This building remained visible from the Sounds Air terminal from which a covered walkway used to link the old terminal to the new one, but has since been removed. An upgrade of the domestic terminal, budgeted at NZ$10 million, was announced in 1981, but by 1983 the plans were shelved after cost projections more than doubled. The terminal was extensively refurbished in 1987 by Air New Zealand, and Ansett New Zealand built a new terminal as an extension to the international terminal when it commenced competing domestic air services in 1987. In 1991, the airport released plans to widen the taxiway to CAA Code D & E specifications and acquire extra space, which were abandoned after protests from local residents. The plan involved the removal of the nearby Miramar Golf Course and a large number of residential and commercial properties. The Airport purchased land from the Miramar Golf Course in 1994 for car park space. As recently as 1992, several alternate sites for Wellington Airport were considered – Te Horo, Paraparaumu, Mana Island, Ohariu Valley, Horokiwi, Wairarapa and Pencarrow – but a decision was made to upgrade the existing site at Rongotai. A major new terminal was completed in 1999 and integrated with the international terminal, which had been built as an abortive first stage of a whole new terminal in 1977. A 90 m safety zone at the south end of the runway was constructed in order to comply with ICAO safety regulations, while a similar zone has been put in place at the runway's north end. Since 1998 the airport has been two-thirds privately owned by Infratil, with the remaining third owned by the Wellington City Council. In late 2003 the airport installed a large statue of Gollum on the terminal in order to promote the world premiere of The Lord of the Rings: The Return of the King. In April 2006, Air New Zealand and Qantas announced that they proposed to enter into a codeshare agreement, arguing that it would be necessary in order to reduce empty seats and financial losses on trans-Tasman routes. The airport counter-argued that the codeshare would stifle competition and passenger growth
