More than five tonnes of books are on their way from New Zealand to Papua New Guinea for three secondary schools in Bougainville.
Otago schools donated books they no longer required and Wellington Rotary clubs helped label, pack and transport nearly 20,000 books.
Hutt City Rotary Club president Murray Brockelsby says they include text books, reading books and class sets of journals.
He says this is the second such shipment. A smaller load was sent last year.
They will be distributed by New Zealand police stationed in Bougainville.
