"Even the most talented artists struggle to make art pay, so when your passion is for painting, your destiny is to draw, how do you pay the rent and put food on the table? You moonlight," she said.
"We have day jobs which are interesting, creative and diverse and, at the same time, we are supporting a creative community and trying to get work out there."
The shared studio has been operating for six years.
Members rent studio space from $25 to $60 a week and exhibit and sell their work separately. But they come together for an annual studio open day and a Dornwell Group show every two years. This year's show at Railway St Studios, Newmarket, runs from June 19 to July 7.
Matthew Browne, of Browne School of Art in Grey Lynn, is a former member.
He is an enthusiast for shared studio space - and for artists working at other jobs.
"When students leave art school or a place of study they are left alone and they can assign themselves not to make art anymore.
"People will go off to try to work on their own but it's very difficult outside a network, or they will find a studio with other people in a building but not bump into anybody.
"However, in a co-operative, self-supporting structure, artists work alongside each other, helping to encourage and support each other to keep working, and it's in a convivial atmosphere.
"There have been studios that do it from time to time but Dornwell have been consistently doing it."
Mr Browne said being part of a collective allowed artists who were not represented by gallery dealers, to encourage the public to come in and talk to them - and perhaps buy their work.
And he said artists who had another job seemed focused.
"If you have less time in the studio, you make better use of time when you are there."
Former part-timer Raewyn Walsh has stayed at the studio despite her jewellery career taking off - she shows her work reflecting contemporary concerns with Masterworks Gallery and is part of an international mentor programme called Handshake.
Three former members are now overseas - in Germany, England and the US and they are doing well with their art.
One of them, Chris Dennis, is working in Berlin and is exhibiting his paintings in St Gallen, Switzerland.
