It will be Vanuatu's first game since a test against Solomon Islands last October.
Harbin said the smaller nations normally didn't get a lot of opportunities to play at the international level.
"It's a pleasant opportunity to see how far we have come," he said.
"We have only been able to play one test a year and this is a great opportunity for not just us, Vanuatu, but all the countries to see how far they are developing and see what else they have to work on and keep developing as minnow nations in rugby league so I reckon it's a great concept. "
