If I remember correctly, the Atlantic was sometimes called 'the Pond' by those who might cross it. The Tasman Sea, which separates Aus and NZ is similarly 'the Ditch', though it is not insignificant. A flight from AKL/WLG/CHC to SYD/MEL/BNE is in excess of three hours. These nine pairs form the main routes, with QF and NZ having a vast majority of the traffic. The contrast in distance between trans-Tasman and European routes is very stark. Less than four hours will get you to Moscow or North Africa.
