"We do well as a small nation on the world never thinking about the ethnicity or religion of those who play alongside us or represent us. We apply that tolerance to sport, but we don't always apply it to our everyday lives.
"I have made assumptions about people. I have assumed that I don't need to know."
The citizenship ceremonies that took place at Te Ahu every six weeks were a reminder that people from around the world wanted to become New Zealanders, "part of us".
"We need to do more to understand who each of us is and who we are," he said.
The ceremony also included a brief message from the Anglican Bishop of Auckland, Ross Bay, delivered by St Saviour's vicar Dino Houtas:
"Now more than ever the people of this land need to join hands with one another across the differences that can divide us, and recommit ourselves to a society that fosters peace and goodwill. The Christian scriptures encourage us to have genuine love for others, and to hold fast to that which is good. Our lives must show those virtues in tangible ways."
