Avery was sentenced to life in prison for the murder of Teresa Halbach
The Netflix series has sparked a social media frenzy which has amassed hundreds of thousands of supporters calling for the release of the 53-year-old.
The show charts the story of Avery, who was wrongly imprisoned for sexual assault and jailed for 18 years before before being exonerated in 2003.
But he was then convicted in 2007 for the murder of photographer Teresa Halbach – which he remains behind bars for.
Filmakers Laura Ricciardi and Moira Demos managed to capture more than two decades of Avery's history with the law and turn it into a riveting 10-part series.
Speaking on the American TODAY programme on Tuesday, Ms Ricciardi said: "[The juror] told us they believe Steven Avery was not proven guilty.
"They believe Steven was framed by law enforcement and that he deserves a new trial, and if he receives a new trial, in their opinion, it should take place far away from Wisconsin."
She added that the juror did vote to convict but only because they "feared for their personal safety."
But more than shedding a light on Avery's case, documentary producers said they wanted to test the American justice system.
Ms Ricciardi said: "Is it delivering on its promise of truth and justice? And we thought Steven Avery would be an amazing window through which to look at the system."
Avery was found guilty of Ms Halbach's murder and was sentenced to life in prison without the possibility of parole.
The documentary casts doubt on evidence used in the trial, including testimony from Avery's nephew Brendan Dassey.
He was 16 at the time and told authorities that he helped his uncle commit the murder.
But he later said the confession was coerced and no DNA of Ms Halbach was discovered at Avery's home – where she was allegedly raped and shot.

Critics, however, claim the documentary is biased and does not tell the whole story.
Ken Kratz, the prosecutor in the murder trial, felt the series painted him "as a villain".
He said: "The people who have vilified me have not taken the time to find out the evidence they weren't spoon fed."
The producers claim they gave Mr Kratz numerous opportunities to speak with them.
The family of murdered Ms Halbach have also voiced their disaproval of the documentary, saying corporations have turned their tragedy into "profit."
In a statement last month they said they saddened to learn that inviduals and corporations continue to create entertainement and to seek profit from their loss.
