"I got to kayak on the Whanganui River, and I loved it. An absolutely highlight of the trail so far was staying at the convent at Hiruharama (Jerusalem)."
Mrs Lunday De Waal said the walk had "had its ups and downs", particularly with the weather, but had overall been a positive experience.
"I'm really enjoying it - I get to meet so many different people."
So far she has raised $10,000 of her target of $30,000.
Time To Thrive - To Stay Alive is a Mangere-based charitable trust which helps people live a healthier, more active lifestyle.

Trail is a growing attraction
Spring is well under way and so are Te Araroa Trail walkers.
They are again passing through Whanganui, with about six hosted at the Tamara Travellers Lodge so far, owner Rory Smith said. He had a total of about 50 pass through last year, mainly in spring and summer.
He's predicting there will be lots more.
"It's going to be an avalanche. It's a huge thing, and it's going to get huger."
The Te Araroa trail runs from Cape Reinga to Bluff, passing down the Whanganui River, then down the coast and heading inland to Palmerston North and the Tararua Range.
Most people walk it from north to south and start it in spring.
