TV3 has signalled that the show 3D is likely to go.
3D's reporting on the Pora case helped his legal team overturn his conviction for the 1992 murder of Susan Burdett.
A video of Mr Pora making the plea has been posted on social media by private investigator Tim McKinnel.
In the video, Mr Pora said 3D had helped many people like him, and asked Mr Weldon "to look into his heart and consider the right decision, keep the programme running".
Mediaworks head of news Mark Jennings said long-form current affairs was challenging, and continuing 3D may not be possible.
