Thousands of customers will be affected by changes to Air New Zealand's flight schedule over the holiday period as the airline has announced its plans to axe a number of international flights.
The airline said the changes are necessary due to ongoing global issues impacting some Rolls-Royce engines on itsBoeing 787-9 aircraft.
The airline said as many as 14,000 customers would be affected by the scheduling changes, and it would be in contact in coming days to arrange alternative flights.
If flights were booked through a travel agent, the agent would be in touch, it said.
The most significant change announced today is the suspension of its twice-weekly seasonal Christchurch-Perth service, resulting in the cancellation of 62 flights.
The airline will also cancel its second daily Auckland-Perth service from 10 December 2019 until 5 January 2020.
Outside the Perth route, a limited number of international cancellations will also take place from 10 December-2 January as follows (all dates given in local time):

The airline said would start processing customers' bookings this week and then start to contact affected customers directly.
Customers booked via a travel agent (including online travel agents) will be contacted by their booking agent.
Customers have been urged to go to Air New Zealand's Travel Alerts section for updates on the issue. The airline will also be using social media to keep customers informed.
Air New Zealand senior manager of customer care and communications Doug Grant said that while the airline never expected to still be facing issues with Rolls-Royce Trent 1000 engines, it's focused on minimising impact to customers.
"Going into the holiday season we're acutely aware how important travel is to our customers, and our schedule changes are designed to keep cancellations to a minimum," Grant said.
"Unfortunately, around 14,000 customers will be impacted by cancellations and we thank them in advance for their understanding."
Air New Zealand has been struggling with issues related to the Rolls Royce Trent 1000 engines since December 2017, when it first secured lease aircraft capacity to help maintain its timetable.
Union responds
E tū, the union for cabin crew, said today that the decision to ground plans could have implications for workers.
"Fewer planes flying means less work and more network disruptions," said the union's head of aviation Savage.
"There is also a risk of some redundancies if 787 crews cannot be redeployed to other fleets or if lease aircraft can't be found to replace the Dreamliners."
Savage said the union would do what it can to ensure efforts are made to redeploy the crew.
He also said the new coincides with wage bargaining for 787 cabin crew.
"We have 650 787 Dreamliner cabin crew in negotiations for a new collective agreement right now and the engine problems have changed the parameters of what has been, at times, a very tense negotiation," he said.
"Cabin crew are an under-appreciated group and disruptions to the airline's performance caused by technical problems outside their control are yet another challenge for them.
"Crew have been through a lot in the two years since the first engine problems were discovered. They are dedicated professionals and they understand how the industry works. However, they do not want to see their working conditions and aviation standards decline even more than they already have."
Air New Zealand said it was working closely with its 787-9 crew and the union to work through how these engine issues would affect its staffing requirements in coming months.
"We are doing everything we can for our crew, including options such as the opportunity to take more annual leave for those who would like to, taking extended leave without pay, working reduced hours or moving to another aircraft fleet where possible," a company spokeswoman said.
What's the problem with the engines?
There are in fact two engine issues. Two parts of about 380 Rolls-Royce engines on Boeing 787s that have potentially serious problems. The "Package C" variants of Rolls-Royce Trent 1000s are on some planes used by airlines including Air NZ, Norwegian, ANA, British Airways, LATAM and Virgin Atlantic. There's been concern about corrosion of turbine blades towards the back of the engines since 2016 and a replacement programme has been in place.
In December 2017, turbine blades on an Air New Zealand flight to Tokyo failed, forcing an engine shutdown. Another engine abnormality the next day forced the airline to ground planes and send engines to Singapore for repairs.
A Transport Accident Investigation Commission preliminary report out last year found the failures happened before they were predicted by Rolls-Royce modelling, but found actions taken since mean extra recommendations are not needed.
How serious is this?
Potentially, very serious. That's why a conservative approach has been taken following the compressor alert. Twin-engine aircraft are designed and certified to fly safely for hours on just one engine if the other fails. But with the Rolls-Royce engines under scrutiny, there are concerns that if used at full power, the good engine may also suffer damage and the Federal Aviation Administration has warned there is an increased likelihood of it failing before a diversion can be completed.
Far from it. The 787 was afflicted by well-known development and manufacturing delays which delayed the Dreamliner's introduction for years past its scheduled entry into service. There were problems with the lithium-ion batteries soon after the planes were introduced, but a fix was found. The plane has since become very popular with airlines and passengers, with promises of extra cabin comfort largely having been met.
Airlines also love the fuel economy of the aircraft, which is about 20 per cent more efficient than those it replaces. Qantas has just signed for six more of them and Hawaiian Airlines switched from Airbus A330s to 787s for its next long-haul plane.
Around 670 Dreamliners are in service and have flown the equivalent of 17 times to the sun and back.
