Police initially treated Mr Tairua's death as suspicious but a post-mortem examination showed he had died of natural causes.
On Sunday family and friends of the man known to many as a "gentle giant" gathered at the Church of Jesus Christ of Latter Day Saints in Manukau to remember him.
His wife Denise called him "my sweetheart", and said he was a man of action, not of words.
Mr Tairua had been married to his second wife for almost seven years, after meeting at church.
Close friend and neighbour Rae Bates told APNZ at the weekend that Mr Tairua was a family man and a dedicated member of South Auckland's Mormon community.
According to his Old Friends profile he had worked as a stevedore at Ports of Auckland since 1974.
His tangi will be held tomorrow.
