UPDATED: Air New Zealand shares close down 2.25% at 87c today, after the airline revealed 441 jobs will be wiped out to help clawback profits.

Flights across the world were delayed this morning (6.40am AEDT) by a technical glitch.

More than one million passengers have flown domestically on Jetstar in less than a year on top of 1.5 million trans-tasman passengers, which the company says is proof of its success in the competitive New Zealand market.

Its chief executive Bruce Buchanan said it was the equivalent of one in four Kiwis choosing to fly with Jetstar.

“When we launched Jetstar in New Zealand nearly five years ago with trans-tasman services from Christchurch, and then almost a year ago with domestic flights, we promised Kiwis real choice.”

Jetstar today announced another service into mainland China, its second in two months and says it has the country in its sights for future growth.

The low-cost carrier will operate the A320 return Singapore-Shantou flight three times a week.

In December last year, Jetstar began direct Singapore-Haikou flights four times a week and the new Shantou flight is the airline’s 20th Asia destination.

A spokesperson said China was a growth market but would not detail any likely future announcements or routes.
