Thomas Nathan agreed to be the getaway driver for his nephew and another person so they could rob a retail giant in Northland of more than $242,000 worth of jewellery and $27,600 in cash and cheques.
He didn't know his nephew, Daniel Cameron, was armed with a cut-down .22 calibre rifle at the time of the aggravated robbery at The Warehouse in Dargaville but once arrested, he offered to help police locate the firearm.
That offer still stands despite Nathan, 39, being sentenced by the High Court at Whangārei yesterday to three years and eight months in jail for his part in the heist.
Cameron, 25, was earlier this month jailed for five years and two months and received his second strike warning which means he'll have to serve his sentence without parole.
He told the court he had been awake for three days due to consuming methamphetamine at the time of the offending.
