Winston Peters says MBIE's size is an issue as he calls for the officials involved in the latest scandal to be jailed.
Immigration Minister Erica Stanford says she was misled about cost increases for a project to upgrade border biometric systems, wasting more than $30 million.
The Public Service Commission is investigating officials’ behaviour.
The New Zealand First Leader told Mike Hosking MBIE is far too big and is covering far too many areas.
He says the computer programme INCIS was a failure, and the National Library computer programme and Transmission Gully both went over-budget.
