The record attempt, from 10am to 11am at Forsyth Barr Stadium, is part of the Wild Dunedin — New Zealand Festival of Nature, and aims to beat the first attempt at Auckland Domain, where 200-300 people participated.
Festival marketing manager Charlie Buchan said it was hoped Dunedin could double that number, and organisers expected hundreds to gather in the stadium.
"The wildlife capital of New Zealand, Dunedin, is set to make history with a bold attempt to break the record for New Zealand’s largest outdoor yoga class.
"In the spirit of the event, don’t be surprised if you hear about new yoga poses like downward-facing hoiho or sea lion pose.
"After all, nature has its own way of stretching."
Mr Buchan said the idea was inspired by the perfect location — the stadium — and the festival's goal to showcase the region’s incredible wildlife and natural beauty, with events over the next 12 days.
"We're lucky to have Forsyth Barr Stadium, which gives us a great setting regardless of the weather.
"You can still feel the grass beneath your feet, but it doesn’t matter if it rains.
"Plus, we wanted to put Dunedin, the New Zealand wildlife capital, back in the spotlight."
The event would also feature a local market with food, crafts and products, alongside performances by Suzy Cato and Anika Moa.
And at 1.30pm, Disney’s Moana will be screened under the stadium’s roof.
He said the aim was to raise awareness and funds for wildlife and nature restoration, protection and conservation efforts in Dunedin.
Festival event manager Carla Munro said the community was already showing great interest.
"This is our 10th year celebrating the Wild Dunedin Festival, and we’re thrilled to see it growing.
"It’s an important celebration of the amazing wildlife and natural beauty we have here in Otago and New Zealand."
