Events include student-teacher debates, themed scavenger hunts, student written plays and skits, seminars with guest speakers, short films, billboard design competitions and flash-mobs.
As well as the memorial balloon release, SADD Wairarapa students celebrated Remember September by hosting an alcohol-free, "Fantasy and Fiction" themed disco at The Spot Youth Centre, to promote safe driving and responsible socialising.
This year, all Wairarapa secondary schools are involved with SADD, which has widened its focus to target the highest risk areas for youth - such as drunk driving, speeding, distractions and general risky driving.
Nationwide, road crashes are the single largest killer of 15 to 24-year-olds - claiming, on average 60 young lives per year and injuring around 3000.
In 2011, New Zealand had the highest road death rate in the OECD for 15 to 17-year-olds. SADD has been active in secondary schools since 1987, and reaches an audience of around 215,000 young people each year.
