Tony and Scott Witty run PlumbSpec out of Kenepuru. Their grandfather ran the trade, their father ran the trade, now they do. Nick joined as a green apprentice five years ago — today he is a qualified plumber, drainlayer and almost-qualified gasfitter. Victoria is one of the few female apprentices in the region and is nearly through her ticket.
