New Zealand's sell-down of state-owned energy companies would gross about $6.8 billion, provided investors agree with the latest valuations by investment banks and research houses.
The valuations, published on the Crown Ownership Monitoring Unit website, are about $2 billion higher than the stock exchange operator, NZX, had assumed in its review of its index methodologies, which was announced last month.
Forsyth Barr valued Solid Energy at $1.69 billion, Macquarie valued Genesis Energy at $1.76 billion and Meridian Energy at $6.53 billion, while First NZ Capital valued Mighty River Power at $3.63 billion for a total of $13.61 billion.
The government plans to sell down its holdings to around 50 per cent.
It also aims to reduce its stake in Air New Zealand to about 50 per cent from 75 per cent, which would net the government some $220 million based on current pricing.
