One of New Zealand’s largest law firms is calling for liquidators to be regulated after one was found by a judge to have fabricated a document.

Te Kauwhata liquidator Geoff Martin had a history of dishonesty, including convictions for tax evasion, theft, fraud and falsifying documents.

Law firm Chapman Tripp said it's time for rules for liquidators.

Chapman Tripp said there's no ‘fit and proper person’ test for liquidators instead no training, qualification, registration or licensing is required.

The firm said New Zealand is unusual in that regard and it needs to change.

Restructuring Insolvency & Turnaround Association chairman Brendon Gibson said members have adopted a self regulation regime.

"Any person over 18, that's not bankrupt, can be a liquidator or a consultancy practitioner. We think is not acceptable and we have been talking to Government about trying to change that."

Mr Gibson said New Zealand should fall in line with other countries.

"You go to the UK, Hong Kong, Australia all of those jurisdictions have licensing regimes and we do see us as being out of step with that."
