If you are flying to Australia from NZ in the first week of April you may need to check connections. When I booked my trip 6 weeks ago the timings did not include the clock change. They do now and as a result I was left with an impossible international / domestic transfer time. It was a bit irritating that I needed to find this out myself (I guess they would have told me in the end but it is a few days before Easter and availability is reducing) and also that I now need to go the previous evening and stay over to make the connection...
