About 200 people wanting to be volunteers at the Rugby World Cup have failed a police check.
Information obtained by Radio New Zealand News under the Official Information Act shows the police have vetted more than 6700 people who applied to be a volunteer during the cup.
Just over 3% of them have not been recommended.
But police refuse to say why. They say that making the information available would be likely to prejudice New Zealand's security or defence, or the Government's international relations.
