WELLINGTON: The New Zealand Rugby Union (NZRU) on Tuesday pledged to fully cooperate with a South African police investigation following an allegation that a member of its under-20s team raped a woman.

The allegations were made on Saturday after a 22-year-old Cape Town woman said she was raped on Friday night, following the team's loss to South Africa in the Junior World Championship.

"Both players and management cooperated fully with the authorities in South Africa," Tew told Radio New Zealand.
