Married at First Sight NZ star Ottie Schwartz has been charged with drink driving.

Schwartz, 32, was granted a registrar's remand at Christchurch District Court this morning.

The promotions manager is charged that on October 28 in Christchurch she allegedly drove on Avalon St with a breath alcohol reading of 473 micrograms of alcohol per litre of breath. The limit is 400mcgs.

Schwartz, who lives in Christchurch, is expected back in court on November 14.

She took to Instagram today and said: "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.

"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."

As some of you will read online on the 27th Oct I was charged with driving over the limit. Unfortunately I made the wrong decision, I have no interest in hiding it & in true fashion I'm owning it. The law is in place to protect people and I would never have driven if I'd thought I was over the limit. It was a routine stop, it had been 3 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. Excuses aside (that's not what I do) 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.

Schwartz has starred in the TV reality show Married At First Sight NZ this season where she was married to apprentice barber Gareth Noble.

Schwartz has previously admitted assaulting a former close friend in an incident at a petrol station eight years ago.

"I had a big falling out with a really close friend of mine and we ended up crossing paths at a gas station," she has said publicly.

"It got very heated. There was some slinging and I ended up pulling her hair - not a fine moment of mine. I wrote her an apology at the time and that still stands. I'm still really sorry about it."

Schwartz said the violent incident ended their friendship, and the two haven't spoken since. No charges were laid.

"I make mistakes like most people do. I think that I still deserve to find love, and I've been really upfront about even the ugly parts of myself, and I'm sure I'll make more mistakes."

Schwartz said she disclosed the petrol station incident to the producers before MAFS NZ filming began.
