New Zealand is punching above its weight in its output of top-quality research, with a new index ranking the country above larger nations like Saudi Arabia and South Africa.
Overall, New Zealand is placed 30th on the just-released Nature Index - tracking high-quality research of more than 8,000 global institutions and assessing the top 10 Kiwi institutions in 2015 by their contribution to 68 leading journals.
In Earth and environmental sciences, one of New Zealand research's major areas of strength, the country ranked 15th in the world.
University of Otago was the highest-placed institution in New Zealand, having made the largest contribution by share of authorship to high-quality papers last year than any other, with the University of Auckland and Victoria University of Wellington placed second and third, respectively.
"The index shows that many of New Zealand's research strengths are rooted in the benefits and challenges of its position on the globe," Nature Index founder David Swinbanks said.
