Kath Hansen and her husband, Stan, will tell how Stan's late father, Bert Hansen, twice escaped from German captivity while serving on the Western Front.
George Owen was filmed at the Otiria Marae explaining how his late father, Arthur, and uncles George and Walter Owen served together in the Maori Pioneer Battalion tunnelling on the Western Front.
Tales will also be screened of the Gallipoli campaign in 1915-16 in which about 480,000 Allied forces took part with more than 250,000 casualties and 46,000 dead, including 2721 New Zealanders.
Museum director Stewart Bowden said visitors could use smaller screens to watch films about key factors in the war while wearing headphones so they don't disturb people watching the big screens. There will be displays of medals and special tables, each of which will hold four iPads set to World War I websites so children can delve into war history.
The Auckland War Memorial Museum is loaning Kiwi North a kiosk in which people will be able to record their family war stories and leave contact details so they can be filmed later.
Mr Bowden said the trench exhibition was expected to remain in the museum for four years, with its collection of local family war stories expanding all the time.
