CanTeen also provided petrol vouchers for travel to and from appointments and would sometimes buy groceries so a family affected by cancer would not have to worry about keeping cupboards full.
The charity would also arrange counselling if needed and help with study or training, in addition to organising workshops and programmes for their members.
Young people aged from 13-24 whose sibling or parent has cancer would also be eligible to join CanTeen as "offspring" or "sibling" members.
The Mega Walk was a very important fundraising event for the organisation, Ms Waby said.

"Because we don't receive any government funding, we get all our funding from donations and fundraising events.
"That money is significant to our budget."
All of the money raised would stay in the local area to provide support to young people in Hawke's Bay.
CanTeen chief executive Claudine Young said community fundraising events were necessary for the charity.
"Events such as the Mitre 10 Mega Walk are absolutely vital to CanTeen.
"It's wonderful to see communities rallying around in aid of 13-24-year-olds dealing with their own cancer, or that of a sibling or parent.
"Fundraisers such as the Mega Walk and the local communities who donate generously to them are critical."
Last year's Mega Walk raised about $19,000, Ms Waby said, but more was raised through events like sausage sizzles on the day.
Over the seven years the Mega Walk funds have been given to CanTeen, the event has raised more than $120,000, all of which went to help for Hawke's Bay teens.
CanTeen offered a number of national programmes to its Hawke's Bay members as well as local support.
One of these was Reset, which was launched earlier this year.
Reset was designed for patients who have finished cancer treatment, to help with nutrition, exercise and returning to normal life.
Ms Young stressed the importance of this approach when the programme was launched.
"Implementing lifestyle changes in a cancer patient's physical exercise levels and ensuring they eat a healthy balanced diet, can greatly reduce the risk of developing another chronic illness and/or secondary cancer."
Reset, like many of CanTeen's programmes, included residential weekend stays for members.
A national appeal for CanTeen was held last month, which was focused on raising awareness of the signs of youth cancer as well as raising funds.
A social media campaign was launched, #ThumpCancer, to spread the knowledge.
"We've seen a huge uptake on social media," Ms Young said.
"Missing the early signs of youth cancer is having a significant impact on the survival rate of young New Zealanders, which lags significantly behind other countries."
This was the first time this kind of appeal has been run - in previous years, CanTeen has ran a bandanna day.
