Ieremia Tienang Tabai (born 16 December 1949) is an I-Kiribati politician who served as the first president of Kiribati from 1979 to 1991. He previously served in the equivalent role, chief minister, under the colonial government from 1978 to 1979. Tabai returned to the House of Assembly in 1998 and represented Nonouti as of his re-election in 2024.

After attending university in New Zealand, Tabai worked in the Ministry of Finance for a year before deciding to enter politics. He was elected to the House of Assembly in 1974 and became the leader of the opposition. Tabai defeated the incumbent Naboua Ratieta to become chief minister in the 1978 election, effectively putting him in charge of independence negotiations, and he became the president of Kiribati upon independence in 1979. He was elected to another term as president in 1982. His term ended abruptly after he tied an unsuccessful bill to a motion of no confidence, but he retained the presidency in the resulting 1983 election. In the early years of his presidency, Tabai made national self-sufficiency central to his agenda.

Tabai signed a fishing agreement with the Soviet Union in 1985, triggering both domestic and international protest. He ran for re-election in 1987, but opposition member Harry Tong filed a legal challenge, saying that Tabai's elections in 1978, 1982, and 1983 meant that Tabai was term-limited. It was determined that the 1978 election was for a colonial position and it did not count against his term limit. Tabai then won re-election. He was term-limited in 1991, so he successfully campaigned for his vice-president Teatao Teannaki to be the next president.

Tabai became Secretary General of the Pacific Islands Forum in 1992, holding the office until 1998. He then returned to parliamentary politics. Tabai founded two media outlets over the next few years: the Newstar newspaper, which was the country's first independently-owned outlet, and a radio station. As an assemblyman, he has opposed Kiribati's relations with China and spoken in favour of smaller family sizes to limit the effects of overpopulation and climate change.

Education Ieremia Tienang Tabai was born in Nonouti on 16 December 1949. He began attending King George V High School in Tarawa when was 11 years old, and he was chosen for a scholarship sponsored by the government of New Zealand to continue his schooling in the country. The change was difficult for him, where he was separated from his family and poorer than the other students, but he credited the experience with teaching him frugality. Tabai attended college at St Andrew's College, Christchurch from 1967 to 1968. Tabai watched the politicians of New Zealand while he was in the country, with Prime Minister Norman Kirk in particular having a strong influence on him. He graduated in 1972 with a bachelor's degree in commerce and administration.

Tabai returned home to the Gilbert Islands in 1973. He was one of the few in Tarawa who had a degree, allowing him to get a job at the Ministry of Finance. He worked there for one year before switching to politics. He married a woman from the Ellice Islands, Meleangi Tabai.

Early political career Beginning his political career, Tabai adopted the politics of Reuben Uatioa. Tabai was elected to represent Nonouti in the House of Assembly during the 1974 general election, and he became the leader of the opposition the following year. For this election, Tabai and his allies called themselves the Democratic Labour Party. He became a strong critic of Naboua Ratieta's government, particularly Ratieta's proposal to create a defence force. The voters saw Ratieta as biased toward northern, Catholic, anti-union demographics, so Tabai's southern, Protestant heritage contrasted him with Ratieta. He presented himself as a common man and an advocate for the outer islands.

Part of Tabai's image was based on his rejection of elitism and protocol; the meetings he held on the outer islands were informal, he often rode the bus, and he was known to ride his bicycle to the shops without a shirt or shoes. Tabai was one of several Pacific leaders of his generation to be shaped by the Nuclear Free and Independent Pacific movement. His habit of taking his son fishing and his willingness to harvest his own coconut sap endeared him to voters.

Tabai led an active campaign against the Ratieta administration, critical of its focus on urbanization at the expense of the outer islands and its decision to create a defence force. He attracted support through his performances in broadcasts of parliamentary debates and by visiting many of the outer islands. The primary theme of Tabai's campaign was that the Ratieta administration was out of touch with the needs of the outer islands and their people. Through his campaigning, he created the impression that Ratieta was ignoring the nation's self-governance and represented a continuation of colonial leadership. After the election, Tabai felt that local issues determined elections more than the national issues that he considered only relevant to South Tarawa.

When the House of Assembly approved a constitutional amendment to establish a popularly elected chief minister, Tabai and three of his allies competed with Ratieta, preventing Ratieta from qualifying for the four-candidate ballot. Accepting that any of them would make an agreeable chief minister, Tabai and Roniti Teiwaki agreed not to campaign around the nation as they were already well-known relative to the other two.

The election for chief minister was held on 17 March 1978, and Tabai won with 55.6% of the vote. Like all of the candidates, he received strong support from the district he represented. The more central location of his district mitigated North–South polarisation, and he received one third of the Catholic vote despite being a Protestant in a religiously divided country. He also received the largest share of the union vote. The youngest candidate of the election, Tabai was only 27 years old when he took the office; although elder status was a significant qualifier in Kiribati, voters prioritised his understanding of government. Tabai later said that his university education, a rarity among the Gilbertese people at the time, gave him an electoral advantage.

Chief minister Tabai carefully balanced his ministry picks when organising his government, ensuring that there was representation for the north, central, and south regions, for both Catholics and Protestants, and for unions. He chose Teannaki as his Vice-President. As chief minister, Tabai was responsible for negotiating the independence of Kiribati. He travelled to London and Washington D.C. in June 1978, leading a delegation that included two ministers, two expatriate civil servants, and two advisers from the Commonwealth Secretariat. Here he negotiated arrangements for financial support from the United Kingdom as the resource that made up the majority of Kiribati's economy, phosphate, was depleted. Also discussed were access to the colonial government's reserve funds, the legal status of Banaba, and American claims in the region. Tabai believed that Australia and New Zealand would be necessary allies after independence, and he criticized them for giving disproportionate aid to the Pacific nations that they had previously held as territories.

As negotiations dragged into October and November, Tabai declared that he would not waver in his opposition to an autonomous Banaba, saying that the Gilbert Islands had the "absolute right to proceed to independence with its territorial integrity intact". He argued this point during the constitutional convention at Marlborough House in November and December. Although the constitution was based on the Westminster system of the United Kingdom, it brought changes to the system that Tabai credited with maintaining the country's stability over the following years, such as an executive president with term limits.

Tabai agreed to an international commission in May 1979 in Suva to address the new constitution and the Banaba issue, further delaying independence. Kiribati achieved independence on 12 July 1979, and Tabai's position of chief minister was renamed president of Kiribati. The large independence celebration was Tabai's first test as the new president, requiring that he manage the many influential figures who visited over the next two days. By this time, he had two children.

Presidency 1979–1982 With an independent nation, Tabai considered it essential that his government could inform the people how the government worked and to get them accustomed to democracy. He was faced with managing an incredibly poor economy between several distant islands, dependent on a foreign nation for its funding. Financial independence became a core ideal motivating the policies of Tabai's government. He enacted a loose policy of austerity with limited spending and moderate privatisation, though he did not enact any spending cuts or tax reform.

Kiribati moved toward a subsistence economy, and it cut funding for public services which included the operation of only a basic primary health care system. Tabai opposed the development of a tourism industry, fearing that the small island nation could be overwhelmed by a surge of wealthy tourists. He instead proposed that they wait "50 or 100 years before talking about such a subject".

Tabai's efforts to promote development and quality of life in the outer islands through the construction of schools and government administration proved unsuccessful. Constitutional law professors Yash Ghai and Jill Cottrell described Tabai's presidency as "quieter" than the neighbouring Pacific leaders who dominated their nations' politics. While president, Tabai continued a practice of climbing a 10-metre-tall coconut tree twice each day to fetch coconut milk, which he said was more economical than buying soft drinks. He considered this a possible career should he fail to be re-elected. Tabai attended the 1979 Commonwealth Heads of Government Meeting in Lusaka shortly after becoming president, where he was the youngest world leader to ever attend a Commonwealth meeting. As president, the United Kingdom granted him an honorary Order of St Michael and St George.

One of the key conflicts of Tabai's presidency began in 1980 when the general workers union Botaki ni Karikirakean Aroia Taan Makuri led a strike. It turned violent, and hundreds of workers lost their jobs. One assemblyman, Bwebwentaratai Benson, passed a motion condemning how Tabai's government handled the strike. This motion was interpreted as a motion of no confidence in Tabai's government, but it failed with 11 votes in favour of the motion and 22 votes against it. The 1982 parliamentary election in March and April became a competition between Tabai's government and the unionists. Of Tabai's nineteen allies in parliament, seven lost their re-election campaigns.

The 1982 presidential election took place on 4 May. Tabai's allies in the House of Assembly gained enough support from independent members to put Tabai and former Vice-President Teatao Teannaki on the ballot, while the unionists aligned with Ratieta's allies to nominate him along with unionist Etera Teangana. Taibai's broad popularity among voters made him a clear favourite to win, and he was re-elected with 48.7% of the vote. His ally Teannaki received 28.5%, further indicating popular support for Tabai's government.
