Trustpower shareholder Tauranga Energy Consumer Trust sold 20 million shares in the power company for $154.8 million as it aims to diversify its investments away from a sole holding in the power company.
The trust reduced its stake to 26.8 percent from 33.2 percent after receiving a mandate from its consumer owners in 2013 to sell down this portion of its holding.
Most of the shares were sold to New Zealand institutions and retail investors, with a small amount bought by Australians.
The price of $7.74 is a discount to Trustpower's $8.08 closing price yesterday.
The shares were halted today pending confirmation of the sale.
