First principal was C.M. Sealey who was succeeded by J. Yolland, during which time the roll increased to 1140. Staff increased to 51 and three new blocks were opened, the administration block featuring a small armoury accommodating rifles for school cadets. A swimming pool and the first gymnasium were constructed, and the two-storey Y block was named Yolland Block. The third principal was F. Forster,.The student based school council was introduced during his tenure. John Kelly introduced mufti as an optional alternative to school uniform in 1974, the first Hamilton school to do so, and only the fourth in New Zealand. He banned caning and introduced the system of deans. The school grew to a maximum of 1425 in 1978. He strongly promoted rowing, rugby and drama productions. He introduced general studies which gave form 6 students opportunity to engage in a wide range of sporting programmes not available at the school, such as sail boarding, clay pigeon shooting, croquet and indoor bowls. Kelly was a keen supporter of overseas aid projects and involved students in fund raising for simple irrigation pumps which could be used in third world nations. The fifth principal was David Hood who continued the policies of John Kelly that he had helped formulate. From Newcastle in England, with a background as a merchant marine officer, Hood was recognised for his inclusive, relaxed style of management. He encouraged new initiatives, including establishment on unused ground of the large stands of radiata pine. He was succeeded by the sixth principal, B. Prestidge in the 1980s before Caroline Bennett was principal during the 90s until 2006. During her time the Māori roll in the school grew from eight percent to 35 percent. The marae complex, initiated by B Prestidge, was completed after a decade. The richly carved wharenui became the base for Ngapurapura, an alternative education programme for Māori students, who were at risk of dropping out of the educational system. The seventh principal was Ashley Brown, who had been deputy principal under Caroline Bennett. He was acting principal for a term but carried out a number of critical reforms such as re-establishing a coherent deans system and making some staffing decisions resulting in a more positive atmosphere in the school. He stayed briefly to assist the eighth principal, Julie Small, who was selected by a new board of trustees, guided by Dennis Finn, a commissioner from the Ministry of Education. She had a reputation for rapidly improving NCEA results at her previous school, Rodney College. In June 2011 Fairfield College made news headlines again due to a prank played 2 years earlier. In May 2009 some one had sprayed six phallic shapes into the grass with weedkiller. As the grass died these shapes became visible. These images were then captured by satellite and published on Google Earth. These images were then republished by media around the world. Sometime before February 2015, however, the phallic images disappeared from Google Maps and the Google Earth software. Richard Crawford was appointed principal for the start of the 2012 year.
2007-2009 disruptions
The school's NCEA Level 1 results improved in 2007 to a 51 percent pass rate but declined to 29 percent in 2008. Former board members Michael Crawford and Winston Pinkerton said this occurred because of "a campaign, by some teachers resistant to change, to undermine the authority and leadership of the principal and the board" which "impacted on teaching and learning in 2008." They said some department heads and others did this when realising their performances would be properly appraised and they would be held accountable for student academic results. "Because of this they began a campaign to undermine the school board and principal, including character assassination of the principal, bullying of other staff and misinformation to media and members of the school community.". In the same article, Fairfield PPTA spokesperson Jennifer Hamilton said she and many of her colleagues were hurt by the comments, and that management of Fairfield staff by the PPTA has been restrained and professional. In 2008 the PPTA advised the MOE that despite the best efforts of the local and regional PPTA to solve the mounting problems, issues were becoming more serious. A MOE appointed negotiator, John Carlyon, was appointed in Term 4 2008 to establish a working party to address problems at the college. During Term 1 2009 there was continued disquiet among some staff, students and parents. Near the end of Term 1 some 10 to 12 percent of pupils went on strike to support teaching staff. The strike received widespread media coverage, and the Waikato Times reported it had seldom received so many complaints, 90 percent in support of staff. The school board resigned. In 2009 management of the school's childcare centre was taken over by the Kindergarten Association of NZ to comply with MOE requirements. Fairfield College has signed up to the Te Kotahi tanga programme intended to improve Maori students academic performance. The 9-year-old programme seeks to change how teachers teach.
