A second large quake has hit the Solomon Islands overnight but no tsunami warning has been issued for New Zealand.
A potential tsunami threat advisory was issued shortly after the magnitude 7.4 quake struck at a depth of 20km at 12.36am.
However, the Ministry of Civil Defence and Emergency Management (CDEM) cancelled the advisory a short time later, saying it was unlikely there was a tsunami threat to New Zealand.
The quake came after a magnitude 8.3 quake struck the Solomon Islands yesterday, prompting a tsunami warning for New Zealand which was also cancelled.
However, CDEM has urged caution due to potentially strong and unpredictable currents around coastal areas of New Zealand, including the northwest of the North Island and the west coast of the South Island.
