Ms Bloomfield (21), who is studying for a masters of entrepreneurship at the University of Otago, came up with the idea of Cooking Bee, which won the Doing Good category in this year's Audacious business challenge.
The category was for ideas that benefited society - for the likes of social entrepreneurs, not-for-profits and sustainable ventures.
The Cooking Bee initiative was targeted at enabling older people and those with minor disabilities to maintain independent living.
Weekly cooking sessions would be provided, where bulk food was prepared with a group of staff and volunteers, enabling participants to take home a range of freezer-friendly meals to eat throughout the week.
The Cooking Bee team, which comprised Ms Bloomfield, Katie Noble and Melissa Barry, received an Audacious prize package valued at more than $2000.
After finishing a design degree at polytechnic last year, Ms Bloomfield decided she needed to ''do something else'' and she wanted to get a degree through university. Friends suggested the masters of entrepreneurship.
The idea of Cooking Bee was born when students had to come up with an idea to use for projects throughout the course. She liked the idea of a business which had the primary goal of helping people.
After winning the Doing Good category, they would now run a free trial, likely to be at the end of the month, to see how Cooking Bee worked and if any improvements needed to be made to the initiative, Ms Bloomfield said.
A menu had already been planned and Ms Noble, who was also a masters of entrepreneurship student, had a nutritionist friend who would look over it before the trial.
Connections had already been established with Age Concern, Arthritis New Zealand and a disability support organisation, while they had free access to the Otago University Students' Association's kitchen.
It was projected in the first year to hold one or two classes a week and that could then increase as its reputation built, Ms Bloomfield said.
Once it was ensured that it worked well in Dunedin, it could potentially be rolled out to other regions.
Ms Bloomfield, who loved cooking, had previously entered Audacious when she was a design student and had been disappointed her ideas had not got anywhere. She was ''stoked'' when Cooking Bee won its category.
She enjoyed her involvement with the programme this year, saying she liked working with other people and found the workshops helpful.
Audacious co-ordinator Kate Turnbull said it had been a ''fantastic year'' for the start-up challenge, with many great ideas and students involved from both the University of Otago and Otago Polytechnic.
''Some just came to the workshops, others entered the challenge and some did both, so it's been great to be able to offer a flexible programme that catered for students at all stages of starting a business.
''We have been focusing on audacious attitudes as opposed to just audacious ideas and we somehow managed to find the perfect bunch of students. Even if it isn't this idea that they get off the ground, they have the right attitude to get the right idea off the ground one day,'' Ms Turnbull said.
One of the judges, David Frame, of ANZ, himself a former entrant in Audacious, was impressed with the quality of the business plans, their detail, and the students' confidence in pitching their ideas, she said.
It was nice to know all the hard work that went into holding workshops and having business coaches available had made a difference to the quality of entries.
The supreme winners, Alice Marsh and Hamish Macintosh, from Thykk Yoghurt, stood out ''right from the start''.
It was a tough choice between the top two, with runner-up Rate My Flat, an online database of rental properties that were rated by their previous tenants, changing the face of student flats ''in a hugely positive way'', she said.
