1866 electoral roll there are 3 HOLMANs in Whangarei area, Charles Henry, Josiah, and John Henry. John Henry address was Abbey Farm Parahaki
Henry Charles HOLMAN late of Whangarei, died 21 November 1893 Ponsonby (which is in Auckland), age 81, so b c1814. He was buried Whangarei
Cemetery records says he was born 30 December 1812 Topsham Devonshire
Find a grave says his wife was Elizabeth Ann who died 1917 age 94
There are a number of children named on family trees and Find a grave but they dont appear to include Josiah or John Henry.
I cannot find anything for those three on passenger lists either, but they are not easy to search!
Papers past 1866 says that the house of Mr HOLMAN of the Abbey Parahaki was burnt down while Mr HOLMAN and family were in Australia

Oh, but a later report says it was the home of Josiah, so I am not sure that helps! Except to show that Josiah and John Henry lived close to each other!
Unless Josiah is the father of John Henry and is the one who died in NSW 1893, and they are this family
