So far Ms Smalley has not offered an apology, saying on Twitter the questions were aimed at getting the minister on the "back foot".
A Facebook post from a student said Ms Smalley had since spoken to a group of university students about the questions, saying: "She is pretty professional and described being highly uncomfortable asking those two questions. She said in hindsight she ought to have listened to her gut, but it was a producer-led interview, not a Rachel-led interview. Still not okay, as Hekia is education minister, so who cares if she is Maori or not. Not a smart question really."
TV3 director of news and current affairs Mark Jennings said they were reasonable questions asked by one of the organisation's most senior journalists.
"They were part of valid question lines around the minister's relationships with her colleagues, and whether her personal views on the Maori electoral seats are out of line with those of the Government."
Jennings did not dispute that the questions could have been driven by the show's producers.
"I'd be surprised if that hadn't been case," he said.
A spokeswoman for Ms Parata's office said they understood the questions were producer-driven and were discussed at Front Page, the production company which makes The Nation, prior to the interview.
Ms Parata had been unaware of the line of questioning.
Ms Parata said yesterday that the Maori question had surprised her and was unsophisticated, but she was "happy to answer any questions put to me".
"I do think it was a rather unfortunate pair of questions. However, that was a discussed approach and one the programme felt was appropriate."
Maori Party co-leader Pita Sharples said the question about Mrs Parata's heritage was an insult.
"I'd be really angry if someone asked me that ... it's questioning your whole being. We value how we see the universe, how we see ourselves, our relationships," he said.
Asking whether Ms Parata was a "bitch" to work for was "disgraceful. It's really derogatory and insulting," he said.
Green Party co-leader Metiria Turei said the Maori question was "unfortunate".
"Maori people don't need to explain ourselves about our whakapapa."
She said it was not appropriate to ask Ms Parata if she was a bitch to work for.
"I have a real problem with Hekia Parata; I think she should be sacked as Minister of Education and I think the fact she has a history of such bad relationships in her office is a relevant issue, but using language like that is not appropriate."
