What is happening in New Zealand?

The illicit marijuana market in New Zealand is worth $131m-$190 m.

A tinny (1.5g) costs $20, no matter which of the main centres you are in. But if you buy by the ounce, you are better off getting your marijuana in Wellington, where it's $296/oz, as opposed to Auckland ($326) or Christchurch ($342) .

It's getting easier to get hold of. 82% of frequent drug users said they can buy marijuana in one hour or less, up from 75% in 2006. 45% said it takes less than 20 minutes.

Most people still buy cannabis from a private house (82%) or a tinny house (49%). But access is growing from other places too. 27% of people got it from a public place like a park, up from 12% in 2009, 17% bought it at a pub or club (10% in 2009), and 8% at their school or tertiary institution (2%). 9% bought it from work, but only 3% went online.

Most frequent drug users got their cannabis from friends (71%) or acquaintances (57%), though buying from drug dealers and gang members is also popular (61% and 35% respectively). Just over 20% bought from family members.
