Air New Zealand expects normalised pre-tax earnings for the year ending June will come in at more than $300 million.
That will be up from $256 million the previous year and $91 million the year before.
The airline's prediction came as it reported a 40 percent jump in net profit to $140 million for the six months to December.
Chief executive Christopher Luxon says the result was driven by a relentless focus on global sales and marketing combined with continuing improvements in costs.
He says the highlight in the result is the ability to reinvest in the business and the result represents an opportunity to do that.
Mr Luxon says it will allow the company to invest in new aircraft, lounges and technology around kiosks and apps.
He says Air New Zealand has good cost control and execution in the marketplace to enable it to drive sales.
