Bashing victim Jack Morrissey died from a pre-existing medical condition and not as a result of the attack on him.
Mr Morrissey, 82, was found dead at his home in Wainuiomata on Friday, less than a month after he was attacked in a home invasion on October 23.
An autopsy indicated Mr Morrissey died of pre-existing medical conditions.
But son Paul said: "You don't have to be a rocket scientist to see it [the home invasion] was a catalyst for a speedy decline in health."
Two teens aged 18 and 14 have been jointly charged with committing aggravated burglary.
