Hon DAVID PARKER: It will grow. The member Barbara Kuriger said it will grow as we push towards 100 percent renewables. Yes, the system will become more reliant on renewables, but, properly designed, the system can cope with that, as it used to in yesteryear. Actually, if you go way back, we had far higher percentage of renewables than we had following the discovery of the big Maui gas finds in the Taranaki region in the 1970s and 1980s. We can have ever-higher percentages of renewables and have security of supply. That same argument used to be run at me when I was Minister of Energy in the 2005 to 2008 period by the Hon Gerry Brownlee, who said we shouldn't have had a target of 90 percent renewables, because that would put at risk security of supply. That wasn't correct, and we're actually up to about 85 percent renewables and doing very well. It was actually good of the prior National Government to continue with that ambition.
