Puckey's fluency and empathy in te reo Māori helped him establish effective relationships and understandings with Māori in Northland. Few other Pākehā in the early years of contact could communicate as effectively between races. Puckey often referred to himself and his wife in his Journals as mere 'labourers in the vineyard', and though he was both modest and humble, the actual effect of his labours may have been under-rated, in his lifetime by Bishop Selwyn, who refused to consider him as a candidate for ordination, ostensibly because of his lack of Greek and Latin, (ignoring his well recognised ability to provide accurate translations of Māori), and by subsequent historians.
