Drug testing of beneficiaries is turning up an extremely low number of results showing drug use - and a lot of missing information about the controversial policy.
Of the 8,001 beneficiaries sent for jobs requiring drug testing, only 22 tested positive to drug use or refused to take tests.
The low number of results has been greeted as a victory by Social Development Minister Paula Bennett, who says the policy is driving beneficiaries away from using drugs.
But her office admits it has no data to support the claim. The scheme began in July and followed employers' concerns about drug use among job applicants. About 40 per cent of jobs listed with Work and Income require beneficiaries to be tested for drug use.
Repeated failure can lead to benefits being stopped for those with no dependants, or cut in half for those with children.
