That includes one charge each of burglary, possession of cannabis plant, driving with excess breath alcohol (third or subsequent offence), and driving dangerously causing injury.
He also admitted four charges of dishonestly using a document, relating to illegally using his father's bank card to make purchases.
The offences were committed between March 30 and April 24 this year.
The incident unfolded about 6pm on March 30 at Pukehina Beach after the victim's wife saw Te Whata leaving a neighbour's vacant property on foot carrying some stolen items.
The victim took chase in his truck and tried to grab Te Whata through his truck window as he ran off before Te Whata broke free and ran to his own vehicle parked down the road.
Te Whata then accelerated, with the victim holding on to the side of the door, before he was spun around and landed heavily on the road.
As Te Whata reversed and drove off, his vehicle struck the victim lying prone on the road.
Te Whata's lawyer Simon Whitehead urged Judge Bidois to impose a sentence of intensive supervision, so his client could take over the care of his two children, living with their terminally ill mother.
Mr Whitehead said Te Whata did not mean to hurt the victim, but became "scared" and struck him as he reversed out to get away.
"It's been a big wake up call and Mr Te Whata is committed to staying on the straight and narrow," Mr Whitehead said.
Judge Bidois said a prison sentence was inevitable, given the number of "aggravating features" to this offending, including Te Whata's past convictions for dishonesty, burglary and drink driving.
