The petition was launched by activist Greg Rzesniowiecki on 5 July. It said the reason behind it was because, "Julian Assange (Wikileaks editor) is under effective house arrest in UK".
"On 5 February 2016, the UN's Working Group on Arbitrary Detention concluded that Assange had been subject to arbitrary detention since 7 Dec 2010."
According to a report on Newstalk, Labor MP Greg O'Connor said he would present the petition to Parliament, even though he personally did not support Assange coming to the country.
At a demonstration in support of Assange in Wellington on Sunday, one protester, Alex Hills, told Newstalk that the world appeared to have forgotten about Assange and this was appalling.
Former US soldier and whistleblower Chelsea Manning spoke at the Embassy Theatre in Wellington on Sunday where the demonstrators had gathered.
Reports in July said that Ecuador President Lenin Moreno had either finalised, or was about to finalise, an agreement with the UK to end asylum protection for Assange. But nothing has eventuated since then.
Ecuador has blocked Assange from using the Internet since the end of March, after he criticised alleged human rights abuses by Spain at the time when Catalonia launched protests for independence.
Assange, who holds both Australian and Ecuadorian citizenship, has been taking refuge in the Ecuadorian embassy in London since June 2012.
