After World War II, the two were combined into a unified trust territory which was granted independence as Papua New Guinea in 1975. The western half of the island, now part of Indonesia was never part of the trust territory.
Togoland (France and United Kingdom) - The French portion became independent as Togo in 1960. The much smaller British portion was merged in 1946 with the British colony of the Gold Coast, which was granted independence as Ghana in 1957.
