Model boundaries for the maximum credible event tsunami modelling carried out for the eastern Coromandel (published between 2013 and 2017) and the Firth of Thames (published 2019), and preliminary modelling (to show tsunami susceptible areas) carried out for the West Coast (published 2015), by eCoast limited. The model boundaries show which areas were included in the modelling. Areas that are outside of the tsunami model boundaries have not been modelled, but may still be at risk of tsunami inundation. For the eastern Coromandel and Firth of Thames the modelling was carried out using the Community Model Interface for Tsunamis (ComMIT) numerical modelling tool. For the West Coast, only preliminary modelling and investigation has been undertaken (as the preliminary results showed that wave heights are likely to be relatively small, and there will likely be time for an official tsunami warning). For more information on tsunami evacuation, including Community Response Plans, the Emergency Management staff for the relevant District Council should be contacted.
