A Kiwi father will walk from Cape Reinga to central Auckland in 10 days to raise money for the Ronald McDonald Charity House (RMHC).

RMHC helps support families by giving them a house to stay in when their child is hospitalised and away from home.

It's a charity which is deeply personal to Vince Scappuci and his partner Jess, as, in April 2018, their 12-month-old son suffered a brain injury.

Baby Leo had a fall at home which broke the back of his skull and caused an internal bleed. That bleed led to brain injury.

"He fell unconscious straight away - that was Friday night and he stayed unconscious for about three days," Vince told The AM Show on Monday.
