"Dunne's comments are hollow words from a hollow man,'' she said.
Mr Dunne said he had opposed the closure of TVNZ7 since it was announced.
He said it was inconsistent for the Government to renew a contract for MediaWorks to broadcast Kiwi FM for six months.
"I think they saw them as just being an elitist, self-obsessed group, when in actual fact they were a large number of New Zealanders speaking out for a role in having a decent public broadcasting system in the future,'' he told morning report.
"What we have from Ms Curran is nothing more than Labour's usual inane `why didn't you bring the Government down over it?' line which they wheel out with monotonous regularity.''
"That is what I call posturing, and more so when you consider that TVNZ7`s fate was all but sealed by Labour in government when it decided the ring-fenced funding it was receiving from NZ on Air was to be contestable,'' he said.
