Air New Zealand NZ2 flies the tropical convective route from London to Auckland. Conditions change hour to hour — view the live forecast for your departure date.
View live forecastThe route crosses mid-latitudes where the polar jet can influence flight conditions, though exposure is shorter than on genuine long-haul crossings. At tropical latitudes, convective turbulence from thunderstorms is the main driver — pilots generally route around storm cells, but afternoon/evening flights encounter more build-up than morning departures. A large portion of the flight crosses open ocean (North Pacific), where upper-level conditions are generally smoother than over continental terrain.
Calmest season: Late spring and early autumn. Transpacific routes are most turbulent in winter months when the polar jet is strong and positioned further south.
Full LHR to AKL route guideAir New Zealand NZ2 operates between LHR and AKL. Whether it’s bumpy depends on the day’s weather — Turbcast pulls live NOAA aviation-grade data so you can check the actual forecast for your departure date rather than relying on averages.
NZ2 is typically operated by the B789. Aircraft swaps happen — confirm with your booking before flying.
