Emergency authorities say they will continue to monitor the threat of a tsunami to the Bay area.
The official tsunami warning was lifted this morning following a major quake earlier today.
Bay of Plenty Civil Defence Group Controller Clinton Naude said: "We will continue to monitor the situation throughout the morning as the unsettled seas may still cause changes to currents, tides and wave patterns."
Mr Naude reminded people on coastal areas to:
• Stay out of the water (sea, rivers and estuaries, including boating activities)
• Stay off beaches and shore areas
• Do not go sightseeing
• Share this information with family, neighbours and friends
• Listen to the radio and/or TV for updates
• Follow instructions of local civil defence authorities
''We have also been advised that residents on the Rangitaiki Plains water scheme are advised to boil water until further notice. This is a precautionary advisory due to high amounts of sediment in the aquifers,' he said.
''Te Teko residents are asked to conserve water due to dropping reservoir levels. Waimana's water supply and Edgecumbe's wastewater are back to normal. For more information about this update please contact Whakatāne District Council.''
8.31am: The tsunami threat that warned Bay of Plenty residents to steer clear of the coast after a major earthquake this morning has been cancelled.
The Ministry of Civil Defence & Emergency Management (MCDEM) has cancelled the tsunami marine and beach threat warning in place for the North Coast Regions of the North Island of New Zealand.
Based on all available data, the greatest tsunami activity has now passed. However, coasts may still experience unusual, strong currents and sea level fluctuations lasting for several more hours.
