The Ukraine flag was flown during an Anzac Day dawn service at Auckland Museum on Monday.
It comes as the war between Russia and Ukraine rages on with thousands killed and injured and millions displaced.
The Anzac event acknowledged the service and sacrifice of all those involved in military conflicts and peacekeeping missions abroad.
Prime Minister Jacinda Ardern and National leader Christopher Luxon attended the Auckland service.
The Ukraine flag could be seen flying atop the museum during the service - at the request of the RSA. The New Zealand, Australian and Union Jack flags were also on display.
Governor-General Dame Cindy Kiro also showed New Zealand's support for Ukraine during her speech at commemorations in Wellington.
"Anzac Day in 2022 finds us weary from the stress of the ongoing COVID-19 pandemic, and witness to disturbing new discord across the world," Dame Kiro said.
"We feel deeply for those suffering in current conflicts. For them, the simple joys of normal life – home and family, work and friends – have been replaced by the daily struggle to keep themselves and loved ones safe. Their new reality is one of trauma, grief, and displacement.
"While there is much that we, as individuals, are powerless to change, as the light of a new day spreads over Pukeahu and Aotearoa, we can resolve to continue to be there for each other, and for all who are affected by war and conflict – past and present."
Prince Charles also alluded to the conflict in a written statement.
"As we pause to reflect on the sacrifice of the Armed Services personnel of Australia and New Zealand in two World Wars, and in other conflicts and peacekeeping operations, our thoughts will also be with those communities around the world who are being torn apart by violence and conflict, and those who are fighting for freedom in the face of oppression," he said.
