Earthquakes in the catalogue prior to the twentieth century are not based on instrumental readings. These have been collated from Māori history and accounts in newspapers, books and diaries. By comparing shaking and damage reports from different towns and settlements, likely epicentres and magnitudes have been assigned. Geological evidence, such as the movement of surface faults or landsliding, can also improve the magnitude estimate, but only the very largest earthquakes leave a fault trace behind. Even once instruments started to be installed in New Zealand after 1884, there were too few of them to comprise a network that allowed earthquakes to be located. It was not until the 1930s that the locations of stations started to form a network, and not until 1942 that it was complete enough to locate some earthquakes with any confidence. Computers were first used in New Zealand to locate earthquake origins and determine magnitudes in 1964.
