Prime Minister Peter O'Neill's office said that the Israeli agency for international development cooperation, Mashav, had confirmed it was ready to assist.
O'Neill says he was in touch with Israeli Prime Minister Benjamin Netanyahu, advising him of immediate needs at the affected areas, including lack of electricity.
Mashav will supply 40 generators, which O'Neill said would provide immediate assistance to communities suffering from damage to critical infrastructure.
"The earthquake has left many locations with no electricity, and restoration of power is essential for these communities. The generators will assist in restoring many vital capabilities, such as the provision of water, medicine, communication and other essential services," he said.
