Meridian shares will be issued at a listing price of $1.50, the bottom of the indicative range of $1.50 to $1.80 and with a much smaller investor pool than the government had hoped for.

Some 62,000 New Zealand investors put their money into Meridian, despite huge efforts through advertising and the structure of the offer to attract retail "Mum and Dad" investors, compared with 113,000 for MightyRiverPower, which listed in May at $2.50 a share, but has traded down to $2.20 since.

The float will raise $1.88 billion after the two instalment payment programme completes in May 2015.

"Bear in mind the circumstances," said Finance Minister Bill English at a mid-evening press conference at the Beehive. "We have the impression a lot of Mum and Dads were scared off by the Labour-Greens policy" as well as uncertainty over the Tiwai Point aluminium smelter and a realisation electricity demand has been falling and the companies are no longer "cash cows".

Meridian will list on Oct 29 on both the Australian and New Zealand stock exchanges, where it will join MightyRiverPower, also partially privatised in May, and Contact Energy, which was sold 100 per cent in private investors' hands in 1999.

The price values Meridian at $3.84 billion for the whole company, compared with around $6 billion when it was last independently valued for the Treasury in 2011. While a large part of the difference is explained by the fact that control remains with the government as 51 per cent shareholder and the previous valuation included higher power prices for supply to the Tiwai Point aluminium smelter, it also reflects the lacklustre retail appetite for the shares.

Labour Party state-owned enterprises spokesman Clayton Cosgrove labelled the float a failure.

"John Key and Bill English's asset sales are officially a farce as Meridian was sold off for $1.2 billion less than they promised and attracted just 62,000 investors," he said.

Numerous factors combined to force down the price of Meridian shares. Chief among these were market fears that a Labour-Greens government, if elected next year, will gut electricity company profits to deliver large price cuts; and ongoing uncertainty about the long term future of the Tiwai Point aluminium smelter.

Revised contracts for the smelter's consumption were concluded in August for a plant that uses around 14 per cent of all electricity produced in New Zealand and accounts for around half Meridian's annual revenue.

On top of that, the fact the MRP share price has fallen from $2.50 at issue in May to $2.20 today prompted major efforts to make the Meridian float as attractive as possible to small-time retail investors, whose appetite for the shares is important to the political success of the privatisation programme.

To that end, the government guaranteed no retail investor would pay more than $1.60 a share, no matter what price was set for institutional investors, and created a two-instalment payment programme, meaning investors will pay $1 now and the remaining 50 cents in May 2015.

Trading from Oct 29 will therefore not be in Meridian shares, but in Meridian instalment receipts, until the shares are fully paid in another 18 months time. This is expected to help stimulate a livelier after-market for Meridian shares than has emerged for MRP.

The government may still press ahead with the sale of Genesis Energy in the first half of next year, assuming market conditions suggest there is appetite for another large, New Zealand electricity company float.

With Contact, Meridian, MRP, TrustPower and network company Vector, half the shares in the top 10 NZX shares are in the electricity sector.

With MRP and Meridian proceeds totalling $3.58 billion, the asset sales policy is likely to struggle to reach the bottom end of the government's $5 billion to $7 billion range, although it has signalled Air New Zealand shares could be sold in a private placement to institutions at any time.

While Meridian will be 86.7 per cent owned by New Zealanders, including the government, but it is clear it has attracted larger retail investors as there is scaling back required for some investors, who will be unable to buy as many shares as they applied for.

Investors who sought more than $20,000 of shares will receive only 55 per cent of what they sought.

Of the 49 per cent of the company sold, some 27.6 per cent comes from foreign institutional investors and 12.7 per cent is from New Zealand institutions.
