Newshub's Connor Whitten wrote an opinion piece following watching My Year With Helen at the Sydney Film Festival.
"She may be New Zealand's most high-profile politician - but being diplomatic is no longer a concern for former Prime Minister Helen Clark. Especially when asked about her previous employer.
"There's a very big glass ceiling," Ms Clark recently claimed.
She was talking, of course, about the United Nations, the job she left only two months ago. It's the first time she's spoken with such cutting candour.
And it shows the spectre of workplace sexism extends to the highest offices in the world.
Ms Clark's collision with the UN's glass ceiling is the subject of a new documentary, My Year With Helen, which premiered Saturday at the Sydney Film Festival.
The film should make Kiwis - men and women - hopping mad."
