Air New Zealand is having a busy year on the route map. After finally getting its full fleet of Boeing 787-9s back in the air (the Rolls-Royce Trent 1000 engine issues that kept several Dreamliners grounded have been resolved), the airline has rolled out six new international services, with more long-haul capacity in the South Island than it has had for years.

The headline-grabber is Western Sydney. When the long-delayed Western Sydney Airport opens near Penrith, Air New Zealand will be the first international airline to land there, starting a three-times-weekly A320neo link from Auckland on October 26, 2026. That will make it the carrier's seventh year-round Australian destination, joining Adelaide, Brisbane, Gold Coast, Melbourne, Perth and Sydney. Unlike the curfew-bound Kingsford Smith, the new airport can run around the clock — worth remembering if you're chasing late arrivals or early departures.

Christchurch is the bigger story for many travellers, though. Long-haul flying returns to the South Island's main gateway after a gap of more than six years, all on the 787-9. Nonstop flights to Singapore start on October 28, 2026, three times weekly, complementing Singapore Airlines' daily service. From November 28, Air New Zealand resumes Christchurch–Tokyo Narita, also three times a week — and it will be the only airline flying nonstop between Japan and the South Island. A third Dreamliner route launches on November 30, linking Christchurch with Perth year-round, running alongside Jetstar's seasonal service during the Southern Hemisphere summer.

Two shorter routes are already up and running. Since May 26, a seasonal A320neo has connected Christchurch with Rarotonga in the Cook Islands, a three-times-weekly winter-sun escape running until October 24. And since June 22, Queenstown has had a seasonal nonstop to Brisbane, also three times weekly, going head-to-head with Qantas, Virgin Australia and Jetstar. For now, the airline has no new routes announced for 2027, so these are the networks to plan around.

Why it matters: this is a genuine boost for anyone heading to New Zealand's South Island. Previously, reaching Singapore or Tokyo nonstop usually meant transiting through Auckland; now Christchurch works as a proper long-haul entry point, which is handy if your trip starts with Queenstown, Fiordland or the Alps rather than the North Island. The Rarotonga link opens up an easy beach add-on to a South Island itinerary, and Western Sydney will give travellers on Sydney's growing western side a far closer airport option once services begin.

For Australians, the Auckland–Western Sydney flights add a seventh direct gateway into Air New Zealand's hub, making onward connections to North America or the Pacific simpler. For New Zealanders, it means more choice in both directions — particularly the Perth route, which restores a direct South Island link to Australia's west coast just in time for summer. Watch the October and November 2026 start dates if you're booking ahead: early fares on newly launched routes are often the keenest.
