Spearman played 19 Tests and 51 one-day internationals for New Zealand, but qualifies as an Englishman due to his Welsh mother.
He moved to England in 2001 to pursue a career in banking, but John Bracewell enticed him to Bristol and he has since been a major part of Gloucestershire's plans.
He did not qualify as an overseas county player, but his New Zealand career meant that he has had to wait three years before becoming eligible for England international honours.
A dashing batsman, he made 341 against Middlesex in 2004, breaking WG Grace's 128-year-old record for the highest score by a Gloucestershire player.
His province Central Districts announced in August 2005 that they were releasing the opener after nine years.
In 2005 Gloucestershire suffered relegation from both Frizzell County Championship Division One and totesport League Division One and the enforced absence of Spearman for an important period of the season certainly hindered the county.
However, the talented batsman still managed to accumulate 930 runs at an average of 34.44 and compiled the biggest Gloucestershire score of the season (216).
He was the county’s leading run-scorer in 2006 first class cricket with a season high score of 192 against Worcestershire.
Gloucestershire awarded Spearman a benefit year in 2008 after more consistent performances during the 2007 season.
But despite six half-centuries in 2009, he lost his place at the top of the order, and had his contract ended a year early at the end of his eighth season at Bristol. It may prove the end to a good career.
