Aged only 20, Hayward was one of the break-out stars of the 2008 Air New Zealand Cup, his debut championship year for Taranaki, scoring three tries in eight appearances. In his first season of first division rugby, picked up two awards – for the most promising player of the year and for back of the year. Hayward's performance didn't go unnoticed by the national media or the Super 14 coaches. He received high praise from television, print and radio commentators. Hayward didn't play in the opening two games and only got his chance as a replacement against Tasman in Nelson. He made an immediate impact with his decisive running and ability to spot a gap. His ability to put a player into space also caught the eye. He finished the year as the first-choice second five-eighth. After an impressive showing in the Air New Zealand Cup in 2008, Hayward was the second-youngest player included on the Highlanders squad for the 2009 Super 14 season. He earned his first Super Rugby start in the Highlanders historic 6–0 victory over the Crusaders in Week 4 of the competition, and made a further 3 appearances as a substitute. In Taranaki, Hayward continued to be a key contributor, appearing in 13 matches and recording 2 tries. He returned to the Highlanders for 2010, Hayward was given an opportunity to start the first two games of the season, but found himself out-of-favour as the season went along, making only 3 substitute appearances the rest of the way. He was one of the more consistent backs of the 2010 ITM Cup, playing every game for the amber and blacks and scored five tries. Hayward was also Top try-scorer for the side and was judged back of the year ahead of finalists Kurt Baker and David Smith. Hayward was not brought back to the Highlanders for the 2011 Super 15 season, and instead signed on with the Hurricanes as a member of their wider training group. He was called up as a replacement for Ma’a Nonu who was serving a one-week suspension, but injuries elsewhere and compelling form made him a permanent squad member from that point on, and seven of his 11 appearances were in the starting XV. Playing his fourth consecutive ITM Cup season for Taranaki in 2011, Hayward broke a New Zealand first-class record – scoring a try in 10 consecutive matches. The run started against Hawke's Bayin September 2010 and ended when he failed to score against Bay of Plenty in August 2011. Nevertheless, there was a bigger prize at season's end; the Ranfurly Shield. After playing his second Super Rugby season in 2012 with the Hurricanes and after 58 appearances for Taranaki, Hayward signed a two-year contract with the Western Force. In 2014 Hayward moved to Treviso, Italy, to play for Benetton Rugby.
