Just booked ARN-SIN / SIN-AKL / CHC-SIN-ARN for £1750, all on SQ except SIN-AKL on NZ.
Who knows how to find the NZ PNR? The one I got from SQ doesn't work on their website!
Very pleased though. I hovered over it for days then bit the bullet. The 45,000 Eurobonus points I'll earn should help take the edge off the cost.
