Under a Helen Clark-led Government, Ms Dalziel held the immigration, commerce, and associate justice portfolios. She described the decision to accept Afghani refugees from the Tampa container boat as a milestone in New Zealand's history, because it showed what a small country could play "when called upon to do so".
Ms Dalziel recalled other lowpoints - her regret as Commerce Minister in failing to fully regulate finance companies which later collapsed, and her resignation from Cabinet after leaking a document relating to the deportation of a Sri Lankan teenager.
She defended the controversial discussion of a "man-ban" in the Labour caucus earlier this year, saying that bloggers which mocked it had done a disservice to the debate.
"I encourage all parties to explore every option to improve women's participation. It does matter that young girls see this as a place they can aspire to serve and they must not find that they are staring through a glass ceiling."

"I remember 23 years ago... I said I wanted to be the face of the people who couldn't be seen and the voice of the people who couldn't be heard. And for a magic moment in time, in the silt-sodden streets of the east of Christchurch, I truly felt that I had lived up to what I entered Parliament to do."
