Soldiers from the Pacific islands were honoured in Anzac Day commemorations at the Auckland War Memorial Museum on Thursday.
More than 450 mostly Niueans and Cook Islanders served with the Maori Pioneer Battalion in World War I.
The museum's senior outreach programmer, Ole Maiava, said their contribution is largely unsung and unknown, even by Pacific people.
Mr Maiava said the museum is inviting Pacific families to use its extensive military records to find out about relatives who fought overseas and to add to the information and photos.
Other events include a slideshow of Pacific soldiers at war, talks by historians about their contributions in overseas conflicts and about the effects of the Pacific war on the islands.
