TO201 Niuatoputapu Group and Niuafo'ou

TO201 Niuatoputapu Group and Niuafo'ou is a nautical chart produced by Land Information New Zealand (LINZ) that covers the northernmost islands of the Kingdom of Tonga.

Chart Overview

This chart replaced the older NZ 8215 as part of a modernization of Tongan maritime data. It provides detailed navigational information for "The Niuas," which are the most remote islands in Tonga, located closer to Samoa than to the rest of the Tongan archipelago.

Geographic Coverage

The chart is divided into several detailed sections (layers) for specific locations:

• Niuafo'ou: An active volcanic island known as "Tin Can Island" because mail used to be delivered in sealed cans thrown overboard from passing ships.
• Niuatoputapu and Tafahi: The main island of Niuatoputapu and the nearby high-peak volcanic island of Tafahi.
• Niuatoputapu Harbour & Entrance: Specialized views for safe entry into the lagoon and harbor area.
