A former top executive at the Government's new mega-polytechnic says it needs a complete reset.

The former Deputy Chief Executive, Merran Davis, is breaking her silence following her resignation last year.

She's revealed she quit because she no longer has trust and confidence in the organisation and is calling for the board to be replaced with an independent commissioner.

Davis told Mike Hosking the organisation needs to involve more people who understand the sector.

She says the board's role was to appoint the right chief executive, oversee progress and manage risks, but they squandered the opportunity to do so.
