The last grand pig master

Whole pigs roasted in an earth oven have been a Chinese tradition since they first arrived to work the goldfields, over 100 year ago. In Palmerston North Rodney Wong rules the roast... Or at least he used to. In recent times the tradition has been dying out. Currently Rodney, who holds the title of Palmerston North's "Last Grand Pig Master" hasn't got an oven. There used to be over a dozen in the region, now there are just three, all inaccessible on private land... Rodney joins Mark Leishman to share the tradition, and his hopes for the future.
