Air New Zealand 1H Profit Up 154%

Air New Zealand's first half profit increased by 154%, reaching $225 million, largely due to low fuel prices. The company forecasts a full-year profit rise of up to 70%, surpassing half a billion U.S. dollars. Their 25% stake in Virgin Australia also contributed to profits. Chairman Tony Carter expressed delight over the performance, which supports expansion into new markets like Houston and Vietnam.
