A petition's been handed to Parliament calling for an inquiry into Alan Hall's wrongful conviction.

Hall spent 19 years in prison wrongly convicted of murdering Arthur Easton in 1985.

He received $5 million and an apology.

The petition asks for a Royal Commission Inquiry into the conviction and police investigation.

Social Justice Aotearoa CEO Jackie Foster says the conviction was a travesty.

"We believe so many questions have not been answered - and no one has been held accountable for what's happened."
