In reply to:
The case of Co^te d'Ivoire is entirely different. This used to be called Ivory Coast in English, then the English name of the country was changed by explicit government decree, and the new name has accordingly been taken up by official bodies such as the UN. What better or clearer reason could there be for you to use the new name of something?
You had best be careful, Nicholas!
From now on, should you have any occasion to mention the name of New Zealand's highest peak, you had jolly well better use its official, government sanctioned, leally recognised name - Aoraki/Mt. Cook. The other NZ peak that Capital Kiwi mentioned is also officially bilingually labelled - Taranaki/Mt. Egmont. Any failure on your part to use these politically imposed designations will be punishable by accusations of inconsistency, accusations fired by me from Aotearoa/New Zealand
