Since 2007, Bon Appétite has catered the PUC Dining Commons; they serve exclusively vegetarian and vegan menu items sourced from local producers, in accordance with Adventist health beliefs and the company's own catering methods.

The college's main library is the Nelson Memorial Library, with holdings of around 150,000 books. It also houses the Pitcairn Islands Study Center, with "one of the world’s largest collections of material" about the islands – according to PUC's General Catalog – as well as literary collections for various figures in Adventist history. In 2011, the library was renovated at a cost of over a million dollars.

In addition to providing the resources necessary for the expansion of the campus in its early years, the forest has also served as a site for biological research and preservation, enclosing as it does unique species and biodiversity.
