The well-intentioned Safe Speed Driver programme, backed by RoadSafe Northland, Whangarei Police, Whangarei District Council and Northland Regional Council, used volunteers to record the licence plates of those making an effort to drive to the conditions during May and June.
Six winners were drawn over six weeks. Until now nobody had claimed their $150 voucher despite widespread publication of the lucky licence plates.
So the organisers came to the Northern Advocate to help and the first two have now been tracked down.
Privacy laws meant police could not use their databases to find the winners.
The remaining plates are TS5313, GFM335, HMU961 and GCR178. Unclaimed prizes expire on July 31.
