In 2005 Virgin Blue Holdings signed an agreement with the Government of Samoa to operate a joint venture airline. The announcement came after several months of detailed discussions between the two parties and involved the Samoan government and Virgin Blue joining forces to set up a new company to operate jet routes previously flown by Polynesian Airlines. The name Polynesian Blue adopted in keeping with the Virgin Blue family of brands, which also included Christchurch based Pacific Blue Airlines. Its first flight was on 31 October 2005, between Apia, Auckland and Sydney.
