What is the subducting plate involved in the formation of the volcanoes of the kermadec islands

Pacific Plate

Explanation:

These islands are volcanic arc formations due to the convergent boundary where the pacific plates subducts under these Indo-Australian plates, so the subducting pacific plate created the Kermadec ridge that runs from north island of New Zealand to Tonga northeast wards. There are several volcanoes that rise from this zone of the sea bed.
