“Dylan had a curly crop of blonde hair, and blue eyes, and a cheeky smile that would light up those around him,” she wrote.
“He was an old soul who had big dreams of doing everything and going everywhere - all tragically cut short.”
Osterfield said Dylan was travelling to Palmerston North with his dad on Friday when the crash occurred.
She wrote that mum Chloe was struggling to comprehend Dylan’s loss, but that the family were immensely grateful for the outpouring of kindness and support.
The crash was one of three fatal crashes on Hawke’s Bay and Tararua District roads over the long weekend.
