The 29-year-old was named in a 2019 trial as allegedly buying methamphetamine and changing currency on behalf of the drug-runners to facilitate purchases.

However, he was not named outside of the courtroom until Friday as he fought to suppress his involvement.

Mr Parker has denied involvement, and has never been charged by police in relation to the matter.

On Friday, he lost a two-year battle to keep his name suppressed.

The Supreme Court judgment hearing the suppression case said "there is no dispute that publication would cause undue hardship to the applicant" but "open justice" must prevail.

Mr Parker is the first New Zealand-born heavyweight boxing world champion, winning the WBO crown in 2016.

The suppression bid, which lasted almost two years, ends a long-running guessing game in New Zealand, with media previously reporting an "international sporting star" was connected to the trial.

The three men charged in the 2016 trial - Tevita Kulu, Tevita Fangupo and Toni Finau - were found guilty of various drug-related crimes and are serving multi-year prison sentences.
