Both victims were rushed to hospital via ambulance.
Annett appeared at Christchurch District Court today for sentencing after earlier pleading guilty to an assault charge.
Defence counsel Kerry Cook said that although Annett was remorseful, he noted that the "totally disproportionate" incident would not have happened if someone had not been breaking in to his vehicle - Annett's "only asset".
A 19-year-old co-offender had earlier been sentenced and ordered to pay $600 in emotional harm repayment.
Judge John Strettell today saw no reason why Annett shouldn't be treated any differently.
He was convicted on the assault charge and ordered him to pay $600 compensation to his victim.
