The system, which has sustained winds of 150 kilometres an hour at its centre, has moved south between Niue and the Cook Islands but is now turning westward.
On its current trajectory, the cyclone is expected to pass about 300 south of Niue and be within about 400 kilometres of Tonga's main island by Friday.
A gale warning is still in force for Palmerston atoll in the Cook Islands.
