Flights mainly to Auckland and Christchurch with a couple serving Brisbane and Sydney in Australia arrive and depart from this airport, 27 kilometers from the centre of New Zealand's 4th largest town, located on the South Island. Though only one is pictured, there are 4 identical installations in this generously-sized men's room."
