New Zealanders expect their Prime Minister to be open, Green Party co-leader Russel Norman says as he pledges to keep asking John Key questions about blogger Cameron Slater.
Last week, Speaker David Carter ruled Mr Key should have given a proper answer when asked in the House about his conversations with Mr Slater.
One in particular was a discussion about the mother of one of the miners killed at Pike River. She subsequently lost a second son, who featured on Mr Slater's blog after being killed in a road accident.
Dr Norman today told reporters it was a matter of principle, which is why he was continuing to pursue it.
"I think it's very important that the people of New Zealand see that their Prime Minister is being truthful," he said.
"The Prime Minister has had a very close relationship with Cameron Slater, who has been engaged in some very unsavoury things.
"I think the people of New Zealand have got a right to know what he's been up to."
