The record for the largest ever yoga class may have been set right here in New Zealand.

It's the first time the record's been attempted, but all in a good cause - to raise money for an emergency treatment centre for people with mental health issues.

Hundreds turned out for the hour long session in the Auckland's Domain this afternoon.

Organiser Franko Heke came up with the idea after a life-altering moment when he found himself contemplating suicide on Grafton Bridge seven years ago.

He found his way back to good mental health through yoga and meditation.

Proceeds from the event will towards suicide prevention.

Exact numbers have yet to be established.
