In a last-ditch effort to appeal his murder conviction, Quinton Winders has had his application for leave to appeal dismissed.
He sought leave to appeal the Supreme Court against the Court of Appeal's decision, challenging his conviction and sentence, but it was thrown out.
Winders was convicted of murdering road worker George Taiaroa near Rotorua five years ago in 2013.
The 46-year-old was sentenced to life imprisonment with a minimum non-parole period of 17 years in December 2016.
He took his case to the Court of Appeal in March, arguing certain parts of evidence should not have been used in the High Court jury trial.
