Faustinah Ndlovu thinks she may have a new world record on her hands, but either way she's happy she's made a difference for children in her home country of Zimbabwe.
Ms Ndlovu walked 21km on Saturday with a 20l bucket of water balanced on her head to raise money for her former school, Domboreshato Primary School, in her homeland.
She said the walk went very well and she did it an hour and a half faster than she predicted, completing it in 3 hours and 33 minutes.
Her route started and finished at the Rotorua Lakefront with a team of supporters tagging along.
"I'm still waiting for the whole Guinness World Record process. I'm not sure about their process, but I have much evidence of photos and videos and I will keep my fingers crossed."
She said she would do it again if she had to prove to the Guinness people she could do it.
So far she has raised $1500 that will go toward building toilets, a well, fencing, chairs and tables for classrooms and establishing a library.
Ms Ndlovu grew up in a small village where carrying water was an everyday task.
"Crossing paths with venomous snakes fetching water was my reality for 25 years in Zimbabwe where I was born and raised," she said on her Givealittle fundraising page.
"I started carrying 20 litres of water on my head when I was only 10 years old."
But, she said the walk was quite challenging since she had been in New Zealand for 14 years and was a bit out of practise - even at home she had never carried 20l of water that far.
