Immigration New Zealand's boss says it's unacceptable staff concerns were ignored.
The Public Service Commission's released its report on the Accredited Employer Work Visa scheme, which began after a whistle-blower alerted the Minister to a lack of checks and balances.
The review has found Immigration New Zealand should have done more to minimise migrant exploitation risk, when regulations loosened post-Covid.
MBIE Chief Executive Carolyn Tremain says concerns were first raised internally last April.
"What has occurred here is not good enough, and we're making sure that we have a two-way conversation with people about issues."
