Right-wing blogger Cameron Slater has taken his campaign against name suppression laws to the Court of Appeal.
Slater was convicted last year on charges of breaching non-publication orders and making a post likely to identify a sexual crime victim, on his blog.
He appealed against the convictions in the High Court, which dismissed the appeal.
The case was heard by the Court of Appeal on Thursday morning.
Slater's lawyer argued that the name suppression orders breached his client's freedom of expression.
The judges reserved their decision.
