Peter Fulton comes from a family of cricketers with his Uncle RW Fulton captaining and playing for Canterbury and Northern Districts, his brothers John, Tim & David, and cousins Sam & Ben all playing cricket throughout secondary school together and junior representative cricket for Canterbury.
Peter Fulton, a tall middle-order batsman nicknamed "Two-Metre Peter", initially made his mark on first-class cricket by scoring 301 not out against Auckland at the Hagley Oval in Christchurch in 2003, which is the highest maiden first-classcentury by any New Zealand batsman. His 9½ hour innings, against an attack containing the Test bowlers Heath Davis and Brooke Walker, contained 45 fours and three sixes. The following 2004 first-class season he scored consistently, making 728 runs at 42.82, including two more centuries, and - after a consistent tour of South Africa with New Zealand A - was called up to New Zealand's one-day squad for the tour of Bangladesh in November 2004. He played one match there, but it was another 12 months before he featured again. Another career highlight was when he scored 112 against in Napier, New Zealand, on 8 January 2006. In the same series he also scored two half-centuries. In March 2006, he made his Test debut against the West Indies. He added 75 in his second match, as New Zealand took an unbeatable lead over the West Indies. In the 2007 Cricket World Cup Fulton was New Zealand's top scorer three times, including a 62 against Australia. He finished with a run tally of 297 at 37.12.
In March 2013 during the third test of the England's cricket tour of New Zealand he made his first International Test century when he made 136. His second International Test century came in the second innings when he made 110. In doing so, he became the fourth New Zealander to score a hundred in both innings of a test match, and the 71st instance and 60th player to achieve the feat in Test cricket.
