Christchurch's NZ Windfarms is on track to finish its $90 million wind farm in Manawatu next year.

In response to shareholder inquiries, the company yesterday released a progress update on the Te Rere Hau wind farm it is developing in a joint venture with a consortium of Australian infrastructure investor Babcock and Brown, and international power company NP Power.

NZ Windfarms chief executive Chris Freear said progress on the site had been helped by settled and dry weather during the summer, but the construction was two months behind what the company outlined in its prospectus.

However, it was on track with predictions made when it released its interim result in December.

Seventeen of the 28 stage two foundations had been poured and were ready for the arrival of the turbine towers.

The first turbine components, four tower sections, would be on site during May and June.

Freear said the installation and commissioning of the stage two turbines was scheduled to commence in the third quarter of this calendar year.

Work was also under way on installing the stage two electrical reticulation within the wind farm and the connection line to the TrustPower substation.
