Bolstad's father, David Bolstad, enjoyed a great rivalry with Wynyard for many years before his tragic death at a wood-chopping competition in 2011.
Bolstad wants to honour his father's memory by doing his part towards a New Zealand team victory.
"I know Dad would be incredibly proud of me for making this team, and it's fantastic having someone like Jason with all his experience - as well as his connection with Dad - alongside me," he said.
Wynyard, who now lives in Auckland but remains a Northland sporting legend as the region's greatest world title winner, said it was a special occurrence having Bolstad in the team.
"Morgan is a very promising up-and-coming axeman, and I know he'll serve both his father's and grandfather's legacy in the sport well.
"I'll certainly help him out in any way I can so that this is a memorable world championship for all the team."
Wynyard was six years old when his late father Pae - himself an accomplished axeman - encouraged his son to take up wood-chopping.
In 1996 he turned professional, and competes in Northland wood-chopping events whenever he can.
