Opoho School pupil Eddie Scott (6) said he raised ''$1100 and something'' to help his mum's cousin, Luke Elliott (33), get medical treatment.
''He's not very well; he got the stroke and now he's going to America to get special treatment.''
As he had never climbed the street before, he had water strapped to his back in a hydration pack and carried a bag of chocolates.
Eddie said he trained for the climb by walking to school with friend Jaspar Schoenleben (6).
The training paid off - Eddie scaled the street with ease, leading an entourage of about 30 people to the top.
Eddie's mother, Anne Scott, said her cousin had a ''massive'' stroke aged 24 and had raised about $22,000 of the $30,000 required to travel to Los Angeles for stroke treatment.
''This is the only hope that he, his wife and his two young boys have had in almost a decade.''
Mrs Scott said she and Eddie were discussing giving to the givealittle.co.nz fundraising campaign and brainstormed the climb idea as a way to raise money from family and friends.
When they agreed on the feat about three weeks ago, Mrs Scott set a $100 fundraising target.
Eddie was aiming higher. ''He said, 'No Mum, we'll get $1000','' Mrs Scott said.
