An Iranian refugee who killed his wife's boyfriend has lost an appeal for a lesser prison sentence.
Mohammad Hamid-Zadeh, then aged 31, stabbed the man to death in the Quadrant apartment complex in Auckland in October 2010, in what the judge described as a prolonged and frenzied attack.
His lawyer appealed against the sentence, arguing that life imprisonment with a minimum period of 12 years six months was excessive, while the Crown appealed for a greater sentence.
The Court of Appeal has ruled in the Crown's favour, increasing the mimimum period behind bars by three years, to 15 years six months.
