"The second side acknowledges those who remained at home, including those that opposed conscription and the call to war. Both are an important part of the history of our country, and our culture," Mr Johnstone said.
Te Puia sales and marketing general manager Kiri Atkinson-Crean said the poppy tribute would be a fitting part of the programme for Opera in the Pa.
"Concertgoers will be invited to place their poppy at the memorial pou at the end of the evening's musical programme, which has been specifically designed to honour the brave men of World War I, showcasing songs from that period."
The Opera in the Pa programme includes popular rallying anthems from the time.
"This year's World War I centenary events focus on the Anzac connection, and this weekend's Opera in the Pa programme will make its own small but significant contribution to the wider remembrance activities," Ms Atkinson-Crean said.
Tickets are available from Te Puia Admissions or online at www.tepuia.com. Entry is free for children under 15 years.
