Author Mark Chamberlain had an immigrant story of his own to tell when he launched his new book, NZ Immigrants: Their Stories at Te Ahu last week.
He was the grandson of an Irish immigrant, a "peasant labourer", who arrived in New Zealand in 1860 to work for his uncle on the main trunk line, he said.
It had been a brutal introduction to the life of a working man, the physical demands at times reducing the young man to tears, but it also laid the foundations for a very successful New Zealand family.
His grandfather, he said, had valued hard work and education, values that had been inherited by succeeding generations.
The family had gone on to produce doctors, lawyers, a High Court judge and even a physics lecturer at Cambridge University.
