Educated at St Bede's College, Nutbrown started his rugby career for Belfast Rugby Club from 1986 at the age of five until 2005. Nutbrown played for Canterbury 2003–2005, in the Air New Zealand Cup, before moving to Bay of Plenty in a swap with Kevin Senio. He then became one of Bay of Plenty's top players alongside New Zealand sevens representatives Solomon King, Nigel Hunt and Zar Lawrence. He played for the New Zealand Under 19s in 2000 and the NZ Colts in 2001 and 2002. Nutbrown was selected for an All Black trial in 2005 and in 2006 played for the Junior All Blacks in the Pacific Nations Cup.
In 2006, he was selected to play for the Chiefs until 2007 and became their second choice Half-back behind All Black Byron Kelleher. When Kelleher left for Europe, Nutbrown was set to become the Chiefs first choice Half-back, but an injury forced him to miss 2007 and the spot was filled by future All Black Brendon Leonard.
Following former All Black Justin Marshall's departure to Montpellier Hérault RC, Ospreys needed a backup to Mike Phillips. In August 2008 half way through the Air New Zealand Cup, Nutbrown left Bay of Plenty for Ospreys. After Phillips suffered an early season knee ligament injury, Nutbrown developed, until Phillips returned from injury in late 2008.
In May 2011 Nutbrown was released by Ospreys and returned to New Zealand signing a three-year deal with the Steamers. Nutbrown was named in the Chiefs 'A' Development Squad 2012 which played matches against Samoan and Fijian 'A' teams Nutbrown was bracketed on the bench for the Hurricanes in their final round robin game versus the Chiefs in Super Rugby on 13 July 2012.
