The decorations, including soft toys, flowers and letters like Waddington's, were controversially bulldozed off 172 graves, and thrown out by council contractors last month.
The council has apologised, but a tearful Waddington was yesterday struggling to deal with what happened.
"I'm still grieving and it's bringing back all those bad memories."
She fears her son's body was disturbed by the contractors and she was considering having his remains moved to Tauranga, where she now lives.
Council parks, sports and recreation acting manager Mace Ward said retrieved decorations were being photographed and unclaimed items would go into storage for at least three months.
The council was also reviewing its processes so the same mistake never happened again.
