The reference was to Mr Mark's infamous words to Korean-born National MP Melissa Lee - and it proved too much for the Speaker of the House, who threatened Mr Scott with expulsion if he interrupted again.
Mr Scott said he wasn't frightened by the warning.
"No, no, no, it happens. It's the job of the Speaker of the House to keep order ... I'm not one to sit there and say nothing."
Mr Scott said he had also tackled Labour MP Phil Twyford "regarding his Chinese sounding names" - in reference to Labour's use of real estate data to claim a majority of Auckland house buyers were offshore.
"We don't do polices based on where someone comes from; we're all Kiwis, mate."
Mr Mark had responded to Mr Scott's words by saying that "the member for Wairarapa does not know; he does not live there. People say that consistently - that is why they come into my office now", Mr Mark said.
Mr Scott rejected the criticism, saying many MPs do not reside in the electorate they represent.
"His own leader can't vote for himself, John Key doesn't vote for himself, Andrew Little doesn't even have an electorate."
With the size of the Wairarapa electorate, Mr Scott says, "If I lived in Waipukurau, Featherston would complain; if I lived in Featherston, Dannevirke would say they need a central Hawke's Bay person.
"So you can't win, if that's the most important thing - which it's not."
Mr Scott said he had more offices in Wairarapa than the National Party has had in the past, and travels the electorate when he is not in Parliament.
"I was in Dannevirke last week and the lower part of the electorate this week. I'm in and around the electorate when I'm not in Wellington."
Mr Scott said he has a toll-free number, which is free unless the caller is using a cellphone. "All they need to do is email me or ring me."
