I would have preferred to fly NZ rather than QF but the fare difference was massive. QF NZL$79 each way, NZ NZL$200+. I did check again this morning before buying the QF tickets. The Air New Zealaned UK site is still showing only the $200+ o/w fares. However, your comment prompted me to check the .co.nz site - lo and behold, this was showing the $79 o/w fares so I've gone ahead and booked AKL-CHC-AKL with NZ (better timings as well).
