Boxer David Tua is believed to have done a secret deal to settle a long-running, multi-million dollar fight with his former management.

Tua has spent the past two days in the High Court in Auckland in a hearing with former trainer Kevin Barry and manager Martin Pugh.

The hearing was held in chambers and unable to be publicly reported.

But a source close to the two-day judicial settlement conference said the parties had reached an agreement that was acceptable to both sides, The New Zealand Herald reported today.

The newspaper said it was believed the settlement resolved all matters and meant the trial scheduled for next year was no longer needed.

Tua has been battling Barry and Pugh since 2003, over court-held money he says is owed to him by management firm Tuaman.
