She said it could be very difficult to get known as a professional photographer.
"Nobody has heard of me here [in Wellington], whereas I've got quite a large circle in Masterton.
"If I want to get my work noticed, that [Fashion Week] would be a really good place to start."
She said photography was something she loved doing and being noticed was just an extra.
"Ever since I was really young, I've always loved looking at photos and it's just always had my interest.
"I have had my camera for three years and, ever since I got my camera, I've just been doing anything and everything."
Ms Riwai-Couch has worked at friends' weddings, which she does mostly unpaid.
"I've had one paid wedding, the second one that I did. I do a lot just so I can get experience out of it and if people want to give koha that's fine.
"I do it because I love to make people happy and I love it when they love what I have given them.
"It's just about growing and learning at the moment and finding my own style."
Ms Riwai-Couch is supported by her husband Ben, who has encouraged her to open up a studio.
"It would be awesome if I could set up a home studio, work from home and do more."
She said her advice to other amateur photographers was just to practise all the time.
"Get out there and keep taking photos all the time.
"When I go somewhere I take my camera, it's all about just doing it as much as you can and loving it."
