"The government share offer program has been an important part of our overall economic plan for New Zealand, in particular by adding more depth and vitality to our capital markets," said Finance Minister Bill English at a listing ceremony Tuesday.
Stock market participation in New Zealand is low compared with many other developed nations. New Zealanders tend to invest more in property, leading to a housing market that the country's Reserve Bank says is overvalued.
But opposition lawmakers have called the asset-sales program a failure and a fire sale. They point to recent independent valuations that indicated Meridian was worth more than the government sales price.
Opponents this year gathered more than 300,000 signatures, forcing a national referendum on whether people support the sales. The result will likely be only symbolic because the government is not compelled to change its plans by referendum.
Meridian Energy is listed on both the New Zealand and Australian stock markets.
