An air traffic control systems disruption which affected trans-Tasman flights was highly unusual and will be the subject of a full review, an independent aviation commentator says.
The IT systems outage
on Saturday night
forced some flights into a holding pattern, while others had to divert or were held on the ground.
Airways New Zealand said the outage affected its main oceanic area's air traffic control system from 4.30pm Saturday, impacting flights in New Zealand and Australia. Air traffic control operations were switched to a back-up system during the outage, before the main system was restored and normal operations were back up by 5.30pm Saturday.
Five flights were held in the air for about 40 minutes during the outage. Three of those were then diverted back to New Zealand and two were able to carry on to their destination.
Airways has yet to provide any details about the cause.
Aviation commentator Irene King, a former Aviation NZ chief executive, said Airways' management of the Oceanic air traffic control system was typically very robust and the glitch was highly unusual.
"They'll be doing a pretty intense investigation as to what went wrong and why. This team are extraordinarily practised, and that's part of the assurance that they provide to the airlines and to the travelling public."
King said she was not aware of any cases like this happening before in the airspace managed by Airways.

Aratere makes its final sailing across Cook Strait today
The Aratere ferry first arrived has been in service in New Zealand since 1999. Photo: RNZ / Samuel Rillstone Interislander ends three decades of history today, when the Aratere 's final sailing departs from Picton this morning. It was announced in April the ferry would stop crossing the Cook Strait to make way for new port infrastructure needed for two new ships set to arrive in 2029. The ferry first arrived on New Zealand's shores in 1999 having been built in Spain at the Hijos de shipyard a year prior and replaced the Aratika, which had been in service from 1974. Maritime Union Wellington Branch Secretary Fiona Mansell worked on the Aratere as a cabin attendant and said it would be "really sad" to see the ship sail into the capital for the last time. "It's kind of like losing something or somebody that's very close to you." Mansell told RNZ the ferry's crew created the best memories onboard it. "They're with each other you know a lot, they become family, not just friends, not just crew mates." The ship's retirement was difficult to deal with, she said. "It's a big loss to the crew, to our membership, to this country, to our city." Cool Tranz truck driver Morgan MacAllister-Robb had been sailing on the Interislander frequently for his 35-year career. Over the past six years he had been onboard the Aratere six days a week - which equated to 312 trips annually. MacAllister-Robb said by a stroke of luck he had a ticket on its last crossing. "I didn't even actually have to plan it, it just happens to be one of my scheduled sailings." He said that the Aratere was his favourite of the three ferries in the Interislander fleet, and that it would be weird to not see it in Wellington and Picton port. In its first months of service, it faced several mechanical problems - including a sailing on 24 February 1999 where it suffered a series of power failures that left it adrift in Wellington Harbour. Days later KiwiRail - then called Tranz Rail - put out a large full page ad in the Weekend Herald which had a picture of the ferry with the text: "Sorry it hasn't been plain sailing".

It led to the introduction of new heavy weather protocols for Cook Strait ferry operators. In late April 2011 the Aratere headed to Singapore for six months for a $53 million 30 metre extension which increased the amount of passengers it could hold from 400 to 650. The work was done by cutting the ship in half and inserting what was called the "mid-body". As part of that work, new propellers were fitted to it which became a focus when two years later the ferry's starboard propeller was lost in Cook Strait. Transport Accident Investigation Commission's (TAIC) chief investigator Tim Burfoot said the propeller was fitted poorly, and that was likely because KiwiRail either did not seek, or follow, expert advice. The propeller from the Aratere was found in Cook Strait after it fell off in November 2013. Photo: RNZ On an evening sailing on 21 June 2024, the Aratere ran aground just outside of Picton with 47 passengers on board. No one was injured, but it triggered another Transport Accident Investigation Commission investigation, with its interim report finding a 36-second auto pilot mistake led to the grounding. The report showed that a new Kongsberg steering system had been installed on the Aratere just weeks prior in May, and 83 inter-island crossings were made in the three subsequent weeks. It also found the crew did not know how to take back control from the autopilot, and it took about two minutes before the ship was brought back under manual control. In April, Rail Minister Winston Peters announced it would be retired due to it being the only ferry where rail freight can roll on and off it. That means it can't use another wharf in Picton while port upgrades there and in Wellington are underway for two new ferries, set to arrive in 2029. At the time Peters said it would have cost $120 million to keep the Aratere in service. The retirement has caused a restructure at KiwiRail with some jobs on the chopping block. In a statement, KiwiRail said that confirmation of what jobs would end and what staff could be redeployed in the company would come at the end of August. It said that a decision had not made on the future of the Aratere post retirement yet and it would lay up at its Wellington berth in the meantime.

'Intense investigation': Air traffic control outage to be scrutinised
An air traffic control IT systems outage to the oceanic area affected flights in New Zealand and Australia yesterday, including this Brisbane-bound flight from Wellington, on which passengers were told the Oceania airspace was closed. Photo: Flight Radar An air traffic control systems disruption which affected trans-Tasman flights was highly unusual and will be the subject of a full review, an independent aviation commentator says. The IT systems outage on Saturday night forced some flights into a holding pattern, while others had to divert or were held on the ground. Airways New Zealand said the outage affected its main oceanic area's air traffic control system from 4.30pm Saturday, impacting flights in New Zealand and Australia. Air traffic control operations were switched to a back-up system during the outage, before the main system was restored and normal operations were back up by 5.30pm Saturday. Five flights were held in the air for about 40 minutes during the outage. Three of those were then diverted back to New Zealand and two were able to carry on to their destination. Airways has yet to provide any details about the cause. Aviation commentator Irene King, a former Aviation NZ chief executive, said Airways' management of the Oceanic air traffic control system was typically very robust and the glitch was highly unusual. "They'll be doing a pretty intense investigation as to what went wrong and why. This team are extraordinarily practised, and that's part of the assurance that they provide to the airlines and to the travelling public." King said she was not aware of any cases like this happening before in the airspace managed by airways.
