Joses Tuhanuku

By 2010, he had become chairman of the Board of Directors of South Pacific Oil, "a company 75 percent owned by the Solomon Islands National Provident Fund (SINPF) which is in turn owned by the workers of Solomon Islands through their NPF contributions". He sought "a full internal investigation into the company's accounts" upon being informed by the company's internal auditor that she suspected its managing director, Mike Hemmer, of misappropriating millions of dollars of funds. Hemmer struck back by accusing Tuhanuku of having sexually assaulted a female manager, drawing media interest to the controversy. Tuhanuku subsequently sacked Hemmer, with the approval of the Board of Directors.

During the 2010 general election, he once more accused candidates of being funded by logging companies.

In 2007, after losing his seat, he became the head of Transparency International - Solomon Islands. Having become Executive Officer of Transparency Solomon Islands (an anti-corruption watchdog affiliated to Transparency International), Tuhanaku was particularly critical of Prime Minister Manasseh Sogavare's government, saying it had not addressed the country's social and economic problems, and had instead done nothing but "waste time with the Attorney-General and the Police Commissioner", in the Julian Moti affair. As Executive Officer of Transparency Solomon Islands, noting the organisation lacked legal means to compel or constrain the government, he stated his aim was to "educate people to understand the problems and put the pressure on the government".

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".

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:

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.

In 1988, he was one of the founders of the Solomon Islands Labour Party, born from the National Union of Workers.

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.

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.
