ANZ to NZRO
One other thing that may work for NZRO is the catchment area of Tauranga/Mt Maunganui. Basically under an hour away, and by that measurement would 'capture' one of the more affluent areas in NZ.
Hamilton was never really an option for the Tauranga crowd, as the journey time to AKL was similar to that of Hamilton.
ROT may work - be interesting to see what 'inbound' they generate direct from Int'l, when AKL is a gateway (and destination) for the larger aircraft that currently service the markets that provide the bulk of the inbound market.
