Death Printout reveals that this is the right John GORDON - thanks MckHa 
I'm pretty sure that The burial minister (of John GORDON - Rev James McMillan C of E) rules out Horohoro

Q: Is the burial place of John GORDON, not noted on the death printout

The information in the Cyclopedia of NZ (Cashmere 1852-53) conflicts with arrival date and I would have expected George to have supplied this information too
The informant to the death (in that era) was
only required to give an indication of how long the deceased had been in New Zealand.
[Do be aware though, that often the "Years in New Zealand" question, can be "quess work" on the part of the informant. ]
