Man critical after motocross jump

A motocross rider remains in a critical condition after falling off his bike at the Pukekohe Motorcycle Club's practice day at Tuakau on Sunday.

It is understood the injured rider is Steven Cunha, a motorcycle mechanic well-known in the area.

He suffered head and abdominal injuries after falling from a height at about 11am and was flown by the Westpac Helicopter in a serious condition to Auckland City Hospital.

A Westpac Helicopter spokeswoman said Cunha was doing a jump on his bike and fell from a height - he was air-borne for quite a distance. 

A staff member from the event said Cunha was well-known to the club and a regular rider.

"He was riding his bike and doing the normal track like he's done in the past," he said. "He's just come off and landed a bit wrong."

The staff member said he was not aware if Cunha broke any bones in the fall.

"We've got an update and he's stable but still critically injured," he said. "They are waking him up today. We're hoping that's all good."

The club day was open to riders of all ages and around 150 people participated, which was not uncommon for the club.

Cunha's brother was also competing, according to Westpac Helicopter staff.
