New Zealand is facing a number of maritime issues on Sunday with the National Emergency Management Agency saying coastal areas on the north and east coast of the North Island and the Chatham Islands may experience strong and unusual currents and unpredictable surges at the shore.
The activity has been caused by the eruption at 4:10am (local time) of the Hunga Tonga-Hunga Ha’apai underwater volcano, located about 65km north of Nuku’alofa, caused a 1.2-metre tsunami.
Tsunami waves of 83cm were observed by gauges at the Tongan capital of Nuku’alofa and waves of 2 ft at Pago Pago, the capital of American Samoa, the Pacific Tsunami Warning Centre said.
