The country has come through a tight electricity generation supply situation this morning.
National grid operator Transpower had to ask the public to conserve energy between 7am and 9am this morning because generators could not guarantee a supply that could meet demand.
Several major power plants had outages for maintenance - taking out about 700MW of generation. Alison Andrew is chief executive of Transpower.
