They have been vocal about the need to address New Zealand's synthetic drugs "epidemic" since Jones died.
Two weeks after Jones' death his mother Lorraine told the Herald he had been doing well since entering rehab.
He had struggled with drug addiction - first cannabis then synthetics - since he was a teenager.
Last year Lorraine and Jones' father Lewis took extreme measures to get him off the drugs - getting a court order to put him into detox.
They told the Herald they were sick of seeing him dribbling, vomiting, incoherent, unable to move, soiling himself and being aggressive and violent while he was high.
After detox Jones was accepted into a full-time rehab centre.
However the day before he died it was decided he should return home and attend the centre's day programme.
Lorraine and Lewis said hours after their son arrived home he was supplied with a fresh bag of synthetic drugs.
The grieving parents were pleased to hear that police had made an arrest.
They said although nothing could bring Jones back to them, they wanted to ensure the people supplying synthetics were stopped so that no other family had to experience the suffering they had been through since September.
Gordon is the fourth person to be charged with supplying synthetics to people who have died in West Auckland in recent months.
Use of synthetic drugs in New Zealand has also been linked to renal failure and heart failure.
