Joses Tuhanuku (born 1 January 1952 in Bellona Island, Rennell and Bellona Province) is a Solomon Islands politician and former trade union leader. He served three terms in Parliament before losing his seat in the 2006 general election.
Having studied at the Papua New Guinea University of Technology and then at the Australian National University, he worked at various times as a secondary school teacher and as a senior lecturer and course coordinator at the Solomon Islands College of Higher Education.
In 1975, he assisted Bartholomew Ulufa'alu in founding the Solomon Islands General Workers' Union, and replaced him as General Secretary the following year and remained the head of the union to this day, when Ulufa'alu was elected to the country's first ever Parliament and became its first Leader of the Opposition. By 1980, the SIGWU had 10,000 members, half the country's workforce, and renamed itself the Solomon Islands National Union of Workers.
In 1988, he was one of the founders of the Solomon Islands Labour Party, born from the National Union of Workers.
He was first elected to the National Parliament in the 1989 general election, as MP for the Rennell-Bellona constituency. He was subsequently re-elected in 1993, but lost in 1997 to Joses Tahua. He won reelection in 2002, but lost his seat in the 2006 election to Seth Gukuna. During those years he was, at different times, Minister for Commerce, Employment, Labour and Industry; Minister for Forestry and Conservation; Leader of the Official Opposition; and Shadow Minister for Finance. In the early 1990s, as Leader of the Opposition, he criticised Prime Minister Solomon Mamaloni, "accusing [him] of failing to acknowledge the extent of the country’s financial difficulties", while the Solomon Islands Council of Trade Unions was demanding Mamaloni's resignation for the same reason.
Tuhanuku has been notably outspoken in denouncing corruption. In 1996, the Australian Broadcasting Corporation described him as "the first ever [Solomon Islands politician] to go public about attempted corruption when he was a minister in the Sir Francis Billy Hilly Government. He was offered $10,000 (SBD) by Tony Yeong, an employee of the Berjaya Group, one of Malaysia's biggest business empires. He refused." Exposed, Yeong resigned and left the country. As Minister for Forestry, in 1994, Tuhanuku "suspended one Malaysian company, Sylvania, from logging near Marovo Lagoon. The reasons were illegal and highly damaging practices." As Minister of Commerce, he deported hundreds of Chinese illegal aliens sparking criticisms from fellow Members of Parliament. Later, as an Opposition MP, he described business leaders in the logging industry in the country as "a bunch of crooks". He stated: "In the logging industry bribing people is part of the industry. They have been bribing ministers of the Government. They bribe landowners. They bribe certain chiefs. They bribe our provincial ministers and so on. So bribery is actually part of the logging industry and the reason is that most of these Malaysian logging companies that operate there, probably that is how they do business. In fact the person who tried to offer me some money, he said that their company, it is a practice in the South Pacific, that they usually give some small present to government people who assist them or facilitate what they are doing in the various countries. So, actually it is a practice that is not restricted to Solomon Islands."
During the riots which followed the April 2006 general election, Tuhanuku claimed that the election had been "corrupted by Taiwan and business houses owned by Solomon Islanders of Chinese origin [who had] bribe[d] the new members and some of the old members to put up" Snyder Rini as Prime Minister. Solomon Islands is one of the few countries to maintain formal diplomatic relations with Taiwan. Shortly before the election, in March, he had published an article in the Solomon Star specifically accusing Taiwan of using corruption "to manipulate and influence the political processes in Solomon Islands, with the sole aim of keeping [Prime Minister] Kemakeza in office". He added: "The issue in question here is one of national significance. And that is the use of so-called 'aid' funds by Republic of China (Taiwan) to manipulate and compromise the political processes in Solomon Islands".
