Ottie Schwartz of Married At First Sight NZ has admitted to being charged with driving over the legal alcohol limit, saying she's annoyed at herself for "making the wrong decision".
The 32-year-old says she was "upset" and leaving an "awkward situation" on the day of the incident, which is also the day the reality TV show's final episode was broadcast.
Schwartz has opened up on Instagram with a lengthy post captioning the phrase, "I disappoint myself".
"I am taking full responsibility for making the wrong decision and I'm annoyed at myself for letting my emotions get in the way of logical thinking," she says.
"I have no interest in hiding it and in true fashion I'm owning it.
"It was a routine stop, it had been three hours since my last drink, I had eaten, and I knew how much I had had to drink. I was upset and thought it was best to leave an awkward situation and go home."

Schwartz also says she wouldn't have gotten behind the wheel if she thought she was over the limit.
In the dramatic finale of MAFS NZ, she and her 'husband' Gareth had a nasty argument, with him telling her to "shut the f**k up".
Afterwards, she told another participant of the show she would knock Gareth "the f**k out", labelling him a "f**king little bitch".
Schwartz was granted a registrar's remand after appearing in the Christchurch District Court on Monday morning and is due to appear again on November 14.
She's charged with driving on Avalon Street in Christchurch with a level of 473 micrograms of alcohol per litre of breath. The legal limit is 250mcg, which brings a traffic ticket, but exceeding 400mcg means prosecution at court.
