Smart meter penetration in New Zealand is continuing to climb and is approaching 42 percent, according to Vector, which provides the majority of advanced meters in the country.
That would place New Zealand in a reasonable position in advanced electricity metering adoption globally.
Smart meter uptake rates in the UK and US are around 30 percent, although smart meters are being made mandatory in much of Europe.
Sweden made intelligent meters mandatory in 2009 and reached 100 percent smart meter rollout the following year. Meanwhile, France plans to have 95 percent smart meter penetration by 2016.
Smart meters track usage in near real time and can report remotely to utility companies using two-way communication.
