Air New Zealand's share price dropped by 14 per cent the opening minutes of trade after the national flag carrier slashed its earnings forecasts for the current year to June.
By 10.10 am Air New Zealand shares were trading at $2.80, down 47c from Tuesday's close.
Air NZ said earlier cut its pre-tax earnings guidance to a range of $340 million to $400 million for the June year, citing the financial impact of the problems that it has with some of its Rolls- Royce engines, and slower-than-expected revenue growth.
The previously announced guidance was for underlying earnings before tax of $425m to $525m, which excluded an estimated $30m to $40m impact of schedule changes prompted by the global Rolls — Royce engine issues.
"The Rolls — Royce engine issues continue to be challenging for the business, both commercially and operationally but are expected to improve as the year progresses," Air NZ said in a market update.
