Hydrographic survey map

This map of New Zealand, produced by the British Admiralty, was based on survey work undertaken by HMS Acheron and HMS Pandora from 1848 to 1855. Measurements of magnetic declination were taken in the many harbours around the coast.

Use the zoom to find the magnetic declination at different latitudes (shown as seven circles).
