Boock was a slow left-arm orthodox bowler and is one of a small number of New Zealanders to have taken over 600 first class wickets.

He made his first overseas tour a few months later in England and in the Test Match at Trent Bridge conceded just 29 runs in a 28 over spell which included 18 maidens and 2 wickets.

In 1979/80, at the dramatic conclusion to the First Test against Clive Lloyd's West Indians at Carisbrook, Dunedin, Boock joined Gary Troup at the crease with New Zealand 100 for 9 and needing four more runs to win this historic match.

[3] In a controversial tour, marred by umpiring disputes and some ugly on field behaviour by the tourists, New Zealand won the series 1–0 after drawing the next two tests in Christchurch and Auckland.

[9] In the 2016 New Year Honours, Boock was appointed an Officer of the New Zealand Order of Merit for services to sport and the community.
