Many courses are often located in beautiful natural settings with some set among coastline & cliffs, forests, lakes, mountains, and even volcanoes. Overseas visitors often remark how the landscape in the North Island looks like one big golf course due to its unulating hills covered in rich green pasture. So it is relatively easy to build courses in New Zealand as the landscape lends itself to the task.
As far as costs go, playing golf in New Zealand is great value. For less than ten dollars you could be playing 18 holes and enjoy a beer on the 19th. For citizens of Japan and other countries it can even work out cheaper to fly to New Zealand and play golf there than play in their own country. Of course, there are world class courses that are not cheap, but there are also plenty of great courses that are almost free to use.
Outstanding world class courses in New Zealand include: Cape Kidnappers, Clearwater, Gulf Harbour, Lakes Resort Pauanui, Terrace Downs, The Carrington, Kauri Cliffs, Millbrook Resort, and Wairakei.
