SIA acquired 25% of a troubled Airline, Air New Zealand in April

its share price to nosedive. The NZ govt was force to bail out and
diluting SIA's share to 5 percent. By Oct '04, SIA estimated to
have lost over NZ$500 mil, according to investment director for
Macquarie Equities. (3)
At the height of the tech boom in '01, SIA showed further
