The Good One Party Register is a Police-led initiative to decrease adverse events resulting from parties in Christchurch, particularly with tertiary students in the Riccarton West area. Set up in February 2014, Good One is a website http://goodone.org.nz/ where anyone can register the details of an upcoming party. After registration, a Police representative usually contacts the party host to talk through party management advice and become a contact point for further enquiries or assistance. In 2015, Good One expanded to north and mid-Canterbury. Over 35,000 party people have attended Good One registered parties in Canterbury since its launch.
