Former Māori Party co-leader Marama Fox has appeared in court on a charge of drink driving.

Marama Kahu Fox, 48, appeared in the Hamilton District Court on Wednesday, where through duty lawyer Mitchell Staub of the Public Defence Service she pleaded guilty to the charge of driving with excess breath alcohol.

Fox was stopped by at a police checkpoint while driving on Grantham St in Hamilton on November 16, where she was tested and found to have a reading of 593 micrograms of alcohol per litre of breath - well above the legal limit of 250 micrograms.

Staub asked community magistrate Terry Bourke not to enter a conviction as he intended to apply for a discharge without conviction for his client.

Fox will return to court to be sentenced on February 4.

Fox was elected to Parliament as a list MP in the 2014 general election and soon after succeeded Tariana Turia as the party's co-leader.

She lost her seat in the 2017 election.

Fox has been in the news again this year, both for a stint on the television show Dancing With the Stars and for the collapse of a failed consultancy business, for which she owes creditors $160,000.

Marama Fox Consultancy Group Tapui was placed into liquidation on August 28, following proceedings at the High Court in Wellington brought by Masterton IT company Ohnyx IT Solutions.
