Former All Blacks halfback Alby Mathewson

Another All Black joins Toulon

He joins fellow All Blacks Luke McAlister, Malakai Fekitoa and Ma'a Nonu at the French Top 14 club.

It's Mathewson's latest stop in a career which has taken him from the Hurricanes to the Blues to the Western Force and domestic stints with Wellington, Hawke's Bay and Canterbury.

He had a stint in England last season with Bristol, but has most recently been plying his trade with King Country in the Heartland Championship.

The 31-year-old, who played four tests for the All Blacks, agreed a deal that includes an option for a second season in the south of France.
