On June 27 of this year Kahika returned to collect it but was advised by the shopkeeper he had sold it.
The Hastings District Court heard yesterday he then punched the owner forcibly in the nose, causing it to break, before jumping over the counter and attempting to again punch the man, who turned and fled the store out a back exit. Kahika went to chase the victim but stopped when another store owner shouted at him to stop.
He then ran back through the store, jumped back over the counter, and left.
Judge Patrick Treston told the court the shopkeeper was left with a badly broken nose that required surgery and had since suffered breathing difficulties.
Judge Treston said the man was "too scared and stressed" to continue trading and had subsequently shut down his business of more than 20 years.
In a victim impact statement, the shopkeeper said the situation had cost him a lot of money and that he and his staff had lost confidence as a result of the attack.
Judge Treston said the statement made for "pretty unhappy reading". He said Kahika had convictions dating back to the 1970s but noted there was none for violent offending.
He said the attack was a "spontaneous eruption of emotion" and acknowledged Kahika had suffered the death of a friend just a day earlier.
Kahika's lawyer, Mathew Phelps, said the offending was not gang-related or pre-planned.
He was sentenced to a term of community detention and ordered to pay emotional harm reparation of $1000.
His victim, who asked not to be named, said he felt the sentence was too soft but did not want to comment further.
