Kiwis are being offered the chance to vote for the colour of Scott Base in Antarctica.
The Scott Base redevelopment will replace the ageing buildings with a fit-for-purpose base powered by 97 per cent renewable energy. It means the building is expected to last at least another 50 years.
The choices of colours are blue, orange or green.
They represent the blue of the glaciers, the green of the Southern Aurora and the orange cheeks of emperor penguins.
Redevelopment project director Jon Ager said the colours evoke landscapes both in Antarctica and New Zealand.
