For reasons that were disputed, this triggered Air New Zealand's Navigation section to resolve to update the McMurdo waypoint coordinates stored in the ground computer to correspond with the coordinates of the McMurdo TACAN beacon, despite this also not corresponding with the approved route.
Por razóns que foron disputadas, isto desencadeou que a sección de navegación de Air New Zealand decidise actualizar as coordenadas do punto de referencia de McMurdo almacenadas no ordenador de terra para que se correspondesen coas coordenadas da baliza TACAN de McMurdo, aínda que isto tampouco correspondía coa ruta aprobada.
