Alcohol interlocks are to become compulsory, for New Zealand's worst drink-drivers.
Under tougher new rules, anyone caught drink driving twice within five years or anyone caught more than three times over the legal limit will receive an interlock sentence.
Gerald Waters has set up a charitable trust, Researching Impaired Driving in New Zealand, on behalf of the friends and family of Katherine Kennedy who was killed by a recidivist drunk driver in 2010.
He's spent his time researching and studying Alcohol and Other Drug impaired driving in New Zealand and internationally.
