A pair of Canada Geese fly by

According to New Zealand Birds Online, the distinctive and well-known Canada Goose / Kuihi is a North American native that has been extensively introduced to UK, Scandinavia, and North Sea nations from Denmark to France, Russia and Ukraine, as well as New Zealand.
Canada geese are widespread in the South Island and most numerous in pastoral areas of the eastern foothills of the Southern Alps from Marlborough to Central Otago, and around coastal lakes and lagoons. Their distribution is expanding in Fiordland and Southland. In the North Island, their distribution still reflects locations at which birds were released during the past 30 years, with the largest concentrations in Wairarapa, Hawkes Bay, Ruapehu-Taupo area, and Waikato.
