Trustpower's generating assets were undamaged and the demerger process was resumed on October 17, with the final High Court judgement approving the demerger scheme of arrangement issued on October 19.
In his judgement, Justice Fogarty noted the demerger had been approved by 99.06 per cent of the shares entitled to vote who voted on the demerger, and 84.81 per cent of the total number of votes able to be cast by all those shareholders entitled to vote.
"It is obvious from the above figures that a very large majority of the shareholders approved the demerger," Justice Fogarty wrote.
Mr Hawksworth said the judgement was the final go-ahead. "There are no other obstacles and it's now a process issue."
Under the demerger arrangements Trustpower shareholders will receive shares in each of:
• Tilt Renewables - which will hold Trustpower's Australian and New Zealand wind generation assets and its wind and solar development projects.
• Bay Energy ("New" Trustpower) - which will continue to operate Trustpower's New Zealand and Australian hydro generation assets and its multi-product New Zealand retail business. Bay Energy will be renamed Trustpower after the current entity is delisted.
Both Tilt Renewables and the new Trustpower will be listed on the NZX main board. Tilt Renewables is also expected to be listed on the ASX.
Trustpower shares are scheduled to cease trading on the NZX on 26 October, with the new Trustpower and Tilt Renewables expected to begin trading on a conditional settlement basis from 28 October.
Normal trading of the new companies is expected to resume on 1 November, though the indicative times are subject to change.
Mr Hawksworth will continue to head up Trustpower, while former Trustpower chief financial office Robert Farron has been designated chief executive of Tilt Renewables.
