They also unfurled a banner, which featured a headshot of John Key and said: "Cut pollution, create jobs? Yeah, nah".
Greenpeace said this was in reference to the "Government's failure to tackle pollution".
It said "thousands" of clean energy jobs could be created if the Government chose to tackle this issue.
The group stayed on the roof for the day.
Speaking outside Auckland District Court today Johno Smith said the group climbed parliament because they believed the Government was not taking climate change seriously.
"In seven years, John Key and his Government haven't introduced one single piece of law to reduce climate pollution," he said.
"That's bad news for our country, our planet, our kids and our economy."
Yesterday's announcement that Solid Energy was to go into administration, would see hundreds of jobs lost, Mr Smith said.
"Hundreds of people may now lose their jobs. If the Government had instead backed our own clean energy industries, we could be looking at thousands of jobs being created.
