Whanganui kart driver Max Rennie had a successful debut in national-level racing over the weekend.
The 10-year-old was in action at the KartSport National Sprint Championships in Upper Hutt.
Sponsor and mechanic Blair Gray said Max qualified for the final and eventually finished 23rd in the 85cc Vortex Mini ROK class.
An accident in front of him hampered progress.
"If there was one more lap he would have cracked the top 20," Gray said.
