Waikato Civil Defence says eastern Waikato coast and Firth of Thames are included in the tsunami marine and beach threat issued after the quake off East Cape this morning.
Flooding of land near shore is not expected but there could be unusually strong currents and unpredictable water flows near shore.
People are advised to stay out of water and away from shore in those areas.
Waikato civil defence group is monitoring the situation closely and will provide further advice as required.
