They may look indistinguishable, but they certainly don't sound the same.
Columba College pupils Holly and Ella Barclay (16) are identical twins and given that they have similar interests such as art, sport, and science subjects, any differences are welcomed.
They also both love languages, but fortunately Holly is a specialist in French and Ella is a whizz in German.
And when fellow pupils are having a little trouble telling them apart, all they have to do is strike up a conversation in French or German.
Passions for their respective languages have grown to the point where they recently became the top New Zealanders in the World Language Perfect Championships - a New Zealand-based annual competition which allows pupils to learn by translating between English and a foreign language while competing with other pupils from around the globe.
Holly finished sixth in the world in the French competition with 28,423 points, and Ella was runner-up in the German competition with 26,043 points - only three points behind the world winner.
They were among more than 225,000 pupils from 12 countries in the competition.
Despite their passion for different languages, neither girl plans to study their respective language at university.
Instead, they both plan to go to medical school and become doctors.
The duo were not the only Columba College pupils to meet with success in language competitions recently.
Modi Deng, Sophie Ray and Ailish Wallace-Buckland (all 16) won the year 12 section of the Young Authors International French Essay Competition, and Ellen Gipp (18) was second in the year 13 section of the competition.
Westlake Girls' High School (Auckland) was second in year 12 and a Wellington Girls' College pupil was first in the year 13 section.
