New police commissioner Mike Bush marked his first day in the top job by joining two constables on the beat in central Wellington, and saying the Roast Busters investigation is in its final stages.
The 54-year-old officially took over from former police commissioner Peter Marshall today, and spoke to media on Cuba Mall during his walkabout.
Targeting drug operations and alcohol-related harm would be top priorities during his term, Mr Bush said.
``In the organised crime space, we are going to continue to focus on the high level offenders, the importers, the dealers, the manufacturers, but we also want to work across a number of agencies to reduce the number of people who are going to get involved in this activity.
``We're looking at how we change the culture around alcohol, because about 50 per cent of our work is caused by alcohol abuse,'' he said.
