Investors' eyes will turn towards Air New Zealand's annual result this month after the national carrier's share price was hammered by natural disasters, soaring jet fuel costs and global economic gloom.
The NZX-listed airline's shares have suffered more than the average for the airline industry - down 28 per cent this year.
The International Air Transport Association, which represents about 230 airlines, said financial markets had marked airlines' share prices down 15 per cent this year.
Jet fuel prices had looked to be trending down from a peak in April but in July rebounded above US$130 a barrel as concerns about supply offset those related to the economic outlook, the association said.
Air New Zealand, which is 74.7 per cent government-owned, in March said it was raising its fares because of rising jet fuel costs - increases which during the previous month had added nearly US$10 million to operating costs.
