Simogun was born in Bargedem in East Sepik around 1900, the son of Haletuo and Yesmari. His parents both died while he was young, and he moved to a copra plantation at Salamaua with his adopted parents. He had no formal education, but joined the Territory of New Guineapolice force around 1930. He initially served in the Kokopo and Rabaul area, before being transferred to Talasea. He rose to become a lance corporal by 1935 and a sergeant by 1939, when he was posted to his home district of Wewak. During World War II he was part of the group of Wewak residents led by Bert Jones that walked to Wau. He stayed in Goroka before being transferred to Port Moresby where he served as a drill instructor. In 1942 he began service as a coastwatcher and was dropped off near Cape Orford by an American submarine in April 1943. Between October 1943 and April 1944 his party switched to guerrilla operations, with Simogun leading attacks on the Japanese, only losing two of his men while killing around 260 Japanese soldiers. His service resulted in the award of the British Empire Medal. Following the war, he returned to the police, before settling in Urip village in 1948. He restarted the village coconut plantation, founded a Rural Progress Society to encourage rice growing, set up his own plantation and worked a truck driver. He also oversaw the building of a new coastal road, later named after him as the Sir Pita Simogun Highway, and established But-Boiken Local Government Council in 1956, serving as its president. He married three times and had eleven children. In 1951 he was selected as one of the three nominated indigenous members of the new Legislative Council. He was reappointed in 1954, 1957 and 1960. Prior to the 1961 general elections he joined the United Progress Party, but failed to be elected from the New Guinea mainland constituency. He contested the Wewak-Aitape Open seat in the 1964 general elections and was elected to the new House of Assembly. Following the elections, he was appointed Parliamentary Under-Secretary for Police. He served in the legislature until the 1968 elections. In 1967 he joined an oil palm settlement scheme, taking the lease of several plots of land in West New Britain, with most of the population of Urip following him. In the 1971 New Year Honours he was awarded an MBE, and he was knighted in the 1981 Birthday Honours. He returned to Urip in the 1980s and died in Boram Hospital in Wewak in April 1987 at the age of 87. He was buried with full military honours in the army cemetery at Moem Barracks.
