Eric Watson says he doesn't have the assets to pay rival Sir Owen Glenn the £29.1 million ($54m) which an English judge ordered him to hand over, a New Zealand court has heard.
Glenn celebrated a major legal victory over his former Warriors co-owner in July when the High Court in England and Wales ruled Watson had engaged in "deliberate deception" when the pair set up a joint venture investment company.
Glenn had seen a large chunk of his fortune tied up in the arrangement, and had spent the past five years fighting in English, Californian and British Virgin Islands courts to extricate himself and his £129m ($250m).
The UK High Court ordered that Glenn's company Kea Investment is entitled to up to £43.5m in compensation from Watson, as well as interest compounding at 6.5 per cent per annum.
Watson has appealed over the interest rate and Kea says if he is successful the compensation awarded will drop by about £20m.
