Hi everyone,

I've booked a return flight to Sydney. My passport expires about three months after the trip. Apparently Australia doesn't have the "your passport must be valid for an extra six months" thing that some countries do, so I didn't expect any issues.

However, Air NZ has sent me a "plan your trip" email, which says to check that my passport is valid for an additional six months. Is this just a generic message that they send to everyone, or is there actually a requirement here that I'm not aware of?

I'm not planning any more trips in the next few years so I don't really want to renew the passport if I don't need to.
