His funeral was held on Friday and his brother, a remand prisoner, was temporarily released so he could attend but failed to return to Mt Eden jail.
"Police are looking for 20-year-old Quade Tai who has a warrant for his arrest for assaulting police and burglary," Counties Manukau police said in a statement.
