ANALYSIS: New Zealand reduced the minimum age for buying alcohol from 20 to 18 in 1999 and, with over two decades of data on the possible effects of the change, some health campaigners are calling for a return to the upper age limit; researchers Alexander Plum, Christopher Erwin and Kabir Dasgupta of the University of Auckland believe the evidence over the impact on crime figures is less than clear.

ANALYSIS: Crime prevention programmes in many countries often adopt a blanket approach to communities, with little regard to race or culture; ahead of next week’s Australia and New Zealand Society of Evidence-Based Policing Conference, researchers Dr Kabir Dasgupta, Dr André Diegmann, Professor Tom Kirchmaier and Dr Alexander Plum discuss their latest study which highlights the role of ethnicity in the criminal behaviour of young fathers, and suggests that a ‘one-size-fits-all’ policy response to crime reduction is likely to fail.
