Each week The Front Page takes you behind the scenes of the biggest story from the New Zealand Herald and Newstalk ZB. Today it's the second wave of meth swamping New Zealand communities. Hosted by Frances Cook.

New Zealand has been fighting meth for 20 years, and yet it's now more available than ever.

A new documentary from the NZ Herald talks to drug users, drug dealers, police and rehabilitation specialists, to get to the bottom of what is going wrong.

The result is a gripping insight into the lives of those struggling with addiction, and the frustration of those fighting a losing battle against the second wave of meth.

For this week's Front Page podcast, I talked to investigative journalist Kirsty Johnston and visual journalist Mike Scott, about how they gained the trust of vulnerable people, and what it was like to work intensively on such a difficult topic for six months.
