Rotorua mayor Steve Chadwick gave the Armistice address.
She said many lives were lost and altered forever on both sides.
"Now in 2018, 100 years on from that first Armistice Day when hopes were so high for enduring peace, we remember those who gave their lives for our country, and also for those who returned home injured in mind and body."
She said the Rotorua Field of Remembrance has been laid every Anzac Day since 2015, and was now in place for Armistice Day.
The centenary of Armistice Day is being celebrated in Rotorua. The Last Post has begun before one minute of silence.
"It is a reminder to us all that those who sacrificed their lives were our boys, our sons."
Chadwick said Rotorua was now a multicultural community and the day was one for everyone to come together and celebrate the peace which was so longed for.
"This is a day to honour those who fought in World War I and to also remember those who sacrificed so much in many other conflicts since."
This fun day for families aimed to replicate the celebrations 100 years ago when news of the Armistice was announced in New Zealand.
It included a range of musical performances, a Multicultural Rotorua Parade of Nations, donkeys to pet and ride, interactive shows by Travelling Tuataras, crafts, old-school games, picnics and the sale of

Rotorua's Alan and Trixie Scicluna said it was important to remember the people who fought in the war and gave their lives up.
"They probably didn't want to, but they had to sacrifice a lot for our country and other countries."
They said there were a great number of people this year and it was a moving ceremony.
The Rotorua District World WW100 Commemorations Committee has overseen the planning of this event which comes at the end of four years of commemorations around World War I.
