Niamh Peren's "Thumbs Up New Zealand" petition closes on October 31.
She needs another 9000 signatures for the Government to take her proposal seriously.
Ms Peren wants any packaging that is 100% recyclable in New Zealand and made entirely from recycled materials to have a label with "two green thumbs up" on it, products 100% recyclable in New Zealand but not made from recycled materials to have "one horizontal yellow thumb" and products that are not recyclable here to have "two red thumbs down".
"The label idea is simple, and leaves no room for loopholes," her petition said.
"Plus, it doesn't exclude those who can't read.
"Sure, it might be embarrassing for companies to come clean about their packaging, but the visual and upfront nature of these labels should inspire them to seek greener solutions."
The petition is on the parliamentary website and Change.org. Between the two, just over 41,000 signatures have been collected.
Ms Peren had also received letters of support from Queenstown Lakes District Mayor-elect Jim Boult, Central Otago District Mayor-elect Tim Cadogan, former Dunedin mayor Dave Cull and Auckland Council environmental and community chairwoman Penny Hulse
In his letter of support, Mr Cadogan said the amount of rubbish sent to landfills in the district was growing.
"I still have the belief that most New Zealanders will do the right thing if they are shown a clear way to do so.
"Niamh's idea for simple and compulsory labelling on all food and drink packaging indicating whether the packaging is recyclable in New Zealand and made from recycled material allows for that and must be strongly encouraged," he said.
Mr Boult believed the proposal made "an enormous amount of sense" and asked for serious consideration to be given to it.
