"When you threaten to eat up all the estate in a legal wrangle so there's nothing to be fighting over in the end, that's the likely outcome. I knew that was going to happen some time back."
Asked whether he stood by his decision to kick Mr Horan out of the party, Mr Peters said "utterly".
"His mother said he was taking money off her wrongly. She put it in a codicil, that's all the evidence I need.
"But there's lots of other evidence why I acted as well."
Mr Horan said he would not comment on personal family matters but told the Bay of Plenty Times he had not considered seeking to be reinstated as part of NZ First.
