Moeroa o Rei Ki Kaikaveka Jack Enoka (3 September 1939 – 4 January 2023) was a Cook Islands politician and member of the Parliament of the Cook Islands.
Enoka was born in Ruatonga on the island of Rarotonga and educated at Avarua School.[1] He was active in the Cook Islands Boys Brigade as a band master, and as a boxer, and worked at the Government Printing office and as a storeowner.[1] In 1977, he was invested with the title of Uirangi Mataiapo.[1]
He stood for Parliament in the 1978 Cook Islands general election and was elected,[2] but the result was subsequently annulled after Prime Minister Albert Henry was found to have corruptly used public funds to fly in voters to influence the result.[3] He stood again in the March 1983 Cook Islands general election, when he defeated Thomas Davis in the electorate of Te-au-o-Tonga.[4] He lost his seat seven months later in the November 1983 Cook Islands general election. He was re-elected at the 1989 election in the seat of Avatiu–Ruatonga–Palmerston, and was appointed Leader of the House.[1] He lost his seat again at the 1994 election. After leaving politics he became a farmer and grew flowers for churches and hotels. He also ran a guesthouse.[1]
He was made an officer of the Order of the British Empire for public services and services to the community in the 2016 Birthday Honours.
