I would never consider a non-maori publication as the source of all information on Ta Moko or Maori culture in general.

Wether they were friends or not.

This is where ignorance bears misrepresentation....

"Much of what we know of the Maori today comes from the studies and documentations made by Major-General Horatio Gordon Robley"

I have never heard of this mans publications. I would be more likely to utilize the paintings of Charles Goldie than this "Head Collector".
