Peat said she had undergone weight-loss surgery herself two and a half years ago, and that was when the idea was born.
"I saw a need for people to have support in keeping that weight off.
"We started in January so it's only a baby business, but things are growing pretty quickly.
"It started off with just me, and we've expanded to employ a nutritionist and a contracted personal trainer."
A registered nurse, Peat said she was on maternity leave and decided she didn't want to go back to shift work.
"This venture isn't without its stresses, but we've a great little team."
Stephen Tier
Chef Stephen Tier has been in the hospitality industry for 45 years.
He said the idea for a safe and hygienic cleaning device for coffee wands - the Wanda a' Clean - came as he passed a coffee machine in a restaurant he was working in.
"A guy by the name of Angelo Moriondo invented the espresso machine back in 1884, so for 137 years cleaning rags have been going into landfills and into the ocean," Tier said.
"This device removes the rags and cloths completely."
The Wanda a' Clean is a handheld unit, and within it sits water and 5-10 millilitres of organic cleaning agent.
"There's a brush in there as well," Tier said.
"You just push it up and down on the wand with the steam going and it totally cleans it."
Mike Petersen
Ecowears is New Zealand's first online subscription service for the rental of sustainably sourced baby clothing.
Peterson, a father of four, said the cost of buying environmentally responsible clothing was far more than "your Kmart polyester type things", and his service would provide another option to buying wardrobes for ever-growing children.
"I've got wholesale prices from New Zealand clothing brands that have an awesome eco story, such as Little Yellow Bird," Peterson said.
"There will be a couple of different subscriptions that parents can sign up to.
"When baby grows out of it you can just order the next size up, effectively.
"We ship that box out and they return the one they no longer need."
Brad Kirkland
Kirkland and his father Tim Richardson have developed an efficient approach to eco-friendly housing - Ecohousing Limited.
Richardson said he had a background in mechanical engineering, while his son was an IT systems business analyst.
"We've combined forces to focus on trying to find a cost-effective housing solution for the New Zealand market," Richardson said.
"Where I come from (Tauranga), you'll pay $800,000 to $1 million in a normal street.
"People can't bridge the gap, construction is out of control, and there are material shortages. If somebody has a little bit of land they can buy one of our units. It's a plug and play type system."
Prototypes were currently under construction, Richardson said.
"Our focus really is on lots of different markets.
"We can build a 30 square metre house that runs on solar, stores its own water underneath, and has a self-contained sanitation system."
Vaughan Campbell
His distillery will produce spirits while simultaneously helping to reduce surplus food going to landfill.
"I'm grabbing that food, mashing it with the help of enzymes and thing like that, and making spirits out of it," Campbell said.
"First off I'm starting with vodka, but I've got plans to expand into liquors and whiskeys.
"Imagine being able to do something for the environment by having a drink on a Friday night."
Campbell said his venture - Good Bones - would be as locally-sourced as possible, right down to the yeast.
"I'm starting off with baked goods, and the amount of baked goods that goes to landfill in New Zealand every year is mindboggling. It's around 11 jumbo jets worth.
Food rots and creates methane, which is 84 times worse for the environment than carbon dioxide.
"If I can take that out of landfill I can stop the damage it'll do."
Sarah Stephens and Sam Duncan
The couple has over 60 working dogs on their farm outside Hunterville, and it was those hungry mouths that inspired their new project - Impact for Dogs dog roll.
"We're staying away from the bulkers and the fillers and making it as 'straight meat' as possible," Stephens said.
"Some dog foods on the market are filled with sugars, flour and grain because it's cheap, it's really cheap.
"We've got a saying that you can't feed the All Blacks on chicken nuggets, and the same goes for working dogs.
"They are like the Olympians of the dog world, and we'd be no good without them, really."
Stephens said they were working with a Massey University nutritionist, who was also a dog specialist.
They have also bought a small dog food business to get Impact for Dogs up and running.
"We're looking to fully launch it next year. Only when it's perfect, though."
Ben Blain
Blain's WellStream app requires users to take an initial quiz of 20 questions to determine their mental wellbeing on a scale of one to seven.
From there, the aim is to gradually improve that score.
"It's a tool for people to actually navigate their own wellbeing lifestyles," Blain said.
His own battles with mental illness between high school and university informed his idea.
"I avoided getting a diagnosis for a very long time," Blain said.
"That was powered by all the stories I'd read about what mental illness was. I thought that as soon as you're diagnosed, you've got it for life."
The starting questions on the app were designed "completely from scratch", Blain said.
"It's something totally new, and not based on anything else.
"When someone's mental wellbeing is low, the app will prompt them to contact one of their trusted supporters, and we've also partnered with 1600 free helplines around the world."
