Te Pou is married to Annie Du, who is of Chinese ethnicity. He told the Herald his wife's name was used to buy the family home during the period covered by Barfoot & Thompson sales data, obtained by Labour.
Te Pou wrote: "I am Maori. My wife is of Chinese descent. My money is not foreign."

His letter to the Labour Party - addressed to leader Andrew Little - cited a section of the Privacy Act which banned the collection of information which would intrude unfairly or unreasonably on individuals.
He said the information had been released from Barfoot & Thompson through a staff member to the Labour Party in a way which was "certainly unlawful". "The use of it to describe Maori New Zealanders as Chinese, 'foreign money', and the cause of a housing problem is certainly unfair."
He wrote to Little telling him one of his children asked: "Daddy, why are people angry at Chinese."
"This demonstrates that actual harm has been caused to our family."
The letter to Little was the first step in seeking redress and was the first step in making a formal complaint to the Privacy Commission.
Te Pou told the Herald Labour was guilty of "racial profiling".
He said the issue of foreign ownership was important and needed to be discussed - but Labour had gone about it in the wrong way.
"It's a conversation we should have had without talking about a particular ethnic group."
He said the decision to isolate and highlight Chinese people went against Labour's core principles.
"They got a lot of Chinese sounding names and basically came up with an equation that I think is not robust but more importantly amounted to racial profiling."
He said he believed Little and Twyford were "decent human beings". "What they have done in this case is just wrong."
Te Pou said he would lay a formal complaint with the Privacy Commission and Human Rights Commission should the party not address his concerns.
