After the 1993 election, the National Party had a majority of only one seat. The appointment of the Speaker, therefore, presented a problem – if National selected a Speaker from among its own ranks, as was traditional, it would lose its majority, since the Speaker was not permitted to vote at that time. Therefore, Prime MinisterJim Bolger decided to offer the Speaker's position to a member of the Labour Party, thereby retaining the crucial vote. Tapsell was the person chosen by Bolger for this role. Despite many objections from his Labour Party colleagues, Tapsell opted to accept the position. His elevation was not unchallenged, however, with an objection being raised by Winston Peters and his New Zealand First party. Peters claimed that his objection was on behalf of the incumbent Speaker, long-serving National MP Robin Gray, who had expected to resume his duties but was now being "cast aside" for political reasons. Critics of Peters, however, claimed that New Zealand First merely wanted to leave National and Labour deadlocked, as it would be New Zealand First that held the balance of power in that situation. Robin Gray, however, refused the nomination, and Tapsell took the Speaker's chair unopposed.
Retirement
In the 1996 election, however, Tapsell lost the electorate, now called Te Tai Rawhiti, by 4215 votes to New Zealand First'sTuariki Delamere, one of the Tight Five. Tapsell had not been put on the party list. This was part of a major shift away from the Labour Party by Māori voters, with New Zealand First capturing all of the Māori electorates. Whether Tapsell would have retained the Speaker's role is uncertain, as a reform of Parliamentary procedure meant the Speaker no longer lost their vote. The loss of his electorate seat, however, prompted Tapsell's retirement from politics. In 1991, Tapsell's family was struck with tragedy when his daughter killed his mother. In the subsequent trial, she was judged not guilty by reason of insanity. In the 1997 New Year Honours, Tapsell was appointed a Knight Companion of the New Zealand Order of Merit, for public services, lately as Speaker of the House of Representatives. After his retirement, Tapsell was involved in a number of organisations, becoming the Patron of Monarchy New Zealand. He also assisted several medical charities, and the University of Waikato awarded him an honorary doctorate in 1997. In 2006, Tapsell spoke at an event with Hak Ja Han, wife of Unification Church leader Sun Myung Moon, and praised their teaching of a "concept of the ideal family as comprising a father, a mother, children and grandparents" living together in a three generation extended family, as being "very Māori."
