Philip, would you please post the details you have which show that Thomas James Joughin went to NZ? I can't find him there, with the only Thomas Joughins being Thomas A. (in the early 1900s), Thomas A. Revd (late 1800s - early 1900s), Thomas Alfred (1890s up to his probate in 1942), Thomas Cannell (probate 1929).
No James Thomas Js - only Alfred James in the 1900s.
There are a "Revd T" and a "T.A." as the parents in school records in 1900 and 1909.
