Due to the time limitations on youtube I had to split the file in 2. The second part I find a little creepy. Hunting around for old bones is sensationalist, the reporter is just a little too keen to find teeth marks in the remains. As for Ngapuhi and cannibalism I might remind you about Hongi returning from one Taua with several hundred heads ina canoe...
This is the first part of the 60 Minutes video on Paul Moon's book "this horrid practice'. The various reactions are interesting. You may like to consider who is biased in this and who looks at history through rose tinted glasses.... I would have liked to see more vigorous investigation by the reporter into the historic records including the horror when Titokowaru reintroduced ritual cannibalism in his campaign.
