Next week, Sarah Wilson will live on just $2.25 a day when she completes the Live Below the Line challenge.
The small sum is the equivalent to the international extreme poverty line, and allows for 75c to be spent on each meal.
The challenge is aimed at giving participants a glimpse into the lives of people living in poverty around the world and raising money for charity.
The mother of three will live below the extreme poverty line for five days in a bid to raise money and awareness of sex trafficking.
Mrs Wilson heard of the Live Below the Line challenge only recently, but her family sponsored a child through the Tear Fund, which triggered her interest.
The Tear Fund, along with other agencies is taking part in the Live Below the Line challenge and has chosen fighting sex trafficking as its cause.
Tear Fund media and communication intern Monique Vallom said there were about 360 participants in the event.
Mrs Wilson had given to the cause previously and this was a way for her to show she was serious about it by ''donating herself''.
She had made an online poster to promote her fundraising and aimed to raise $500 in total.
She will also sell home-made lemonade on her street to fundraise.
Although she would not starve, it would still be demanding.
Her biggest challenge would be going without coffee for the five days.
''I love coffee; it's going to be quite a challenge.''
With three children, aged 2, 4 and 7, she would probably still cook meals for them while she completed the challenge, but might turn to One Helping Cookbook.
It was developed with the help of well-known Kiwi chefs, who created 40 recipes for meals that cost 75c per helping to make. All proceeds from the cookbook sales will go towards the fight against sex trafficking.
