New Zealand is the only non-European country to rank inside the top 10 on the most recent annual world energy performance index.
Parliamentarians from across the political divide are welcoming the placing, with Energy Minister Megan Woods saying the ranking is a "strong endorsement of New Zealand's energy system and the approach our country is taking."
According to the World Energy Council's Energy Trilemma index, New Zealand energy performance is the best in the Asia-Pacific region.
New Zealand came in eighth, up one place on last year, between Norway (9th) and Germany (7th).
The Index ranks 130 countries on how well they are achieving a balance between energy security, energy equity and environmental sustainability.
