Jinyue Yang who is acting as advocate for convicted meth smuggler Guowei Deng. He was convicted in New Zealand’s biggest-ever meth trial. But after 13 years in prison, exhaustive attempts at clearing his name and a return to China, Guowei Deng says he lives to prove his innocence. Steve Kilgallon and Lucy Xia report. For Guowei Deng, jail was a particularly solitary experience. For years, he believes he was the only Chinese inmate at Paremoremo, the high-security prison near Auckland. The only English language he had was picked up from fellow convicts he worked alongside in the laundry, factory, and kitchen, where he liked cooking them Chinese food.
