New Zealand captain Daniel Vettori said he opted to give England batsman Paul Collingwood a life "in the spirit of the game" as the Black Caps won by four wickets with 22.5 overs to spare in a Champions Trophy clash at the Wanderers on Tuesday.

Underdogs in Group B, the Black Caps won two round robin matches to top the standings on net run rate and join England, who also won twice, in the semi-finals.
