An international celebration of nature, based in Dunedin, is planned for 1990. Television New Zealand's inaugural Pacific festival of Nature Films, scheduled for the end of November that year, is to coincide with an international bird preservation conference in Hamilton, and in Christchurch, the 20th International Ornithological Congress. The year 1990 will see the Commonwealth Games, the 150th anniversary of Government in New Zealand and the 50th birthday of the country's ornithological society. Up to 1000 people are expected at the Ornithological Congress in Christchurch. TVNZ expects up to 300 of them to attend the five-day festival, and about 200 film and television documentary makers to submit their work. The IOC is also planning an international photographic challenge and a stamp exhibition. The 50th International Council for Bird Preservation is pencilled in for Hamilton in November 1990. Details of the down-under nature festival are still sketchy, but a feasibility study is nearly complete.
