Air New Zealand Air Points - Flight schedule anomalies on www.airnz.co.au

I was just checking the SYD AKL flight schedules for 29/11 and it reads 3 x A320 and 1 x 74E ( which appears to be a non fitted 744). However, when i went to a dummy booking it says 2 x A320, 1 x 74E & ! X 772!!! I have noticed this happening a bit recently . Anyone else noticed????

Some AKL-SYD services are scheduled to be operated by 777s starting in November. I'm booked on one for NZ103 on Jan 3rd so looking forward to checking out the new aircraft. I'd guess the anomaly you saw is because the flight is normally scheduled to be operated by a 320, but has recently been changed to a 772 for certain dates.
