The Herald on Sunday visited the electorate shortly after the resignation was announced.
"I'm very upset about it, actually, because she's such a good minister," said John Smith.
Christine Baty was also unshaken in her support for the embattled MP.
"We need somebody stirring and feisty," she said.
"She's in your face. I like having somebody like that there."
But Sanjay Arora said her resignation was "about time".
"She should have been sacked earlier. I don't know why John Key took so much time."
Rita Rai said she voted for Collins at the last election but would not do so again.
"Things have been a little too murky."
The Dirty Politics scandal has tarnished Collins in Danny Cairns' view.
"When she first started I actually thought she was quite good, even though I didn't vote for her. After what's happened over the last few weeks, I'm glad she's gone."
At the time of her resignation, Collins released a statement strongly denying any suggestion of inappropriate behaviour, and vowing to continue her campaign for the Papakura vote.
"I am a strong advocate for the people of Papakura and I will continue to put the same passion and energy into representing them.
"I am getting on with my job as MP for Papakura and will campaign strongly for re-election this year," Collins said.
