Many Russians were in the crowd, standing shoulder to shoulder with Ukrainians.
"Russians don't want the war," one speaker said.
Russian-born couple Valera Terentev and Lisa Terenteva, who have called Christchurch home for the last six years, are appalled at the war.
"We want to show our support not only for Ukraine but for the world against this lunatic Putin and his team who collectively are aggressive against Ukraine, the western way of understanding, democracy, freedom, intellectual development and progress," Valera said.
Other signs included "Adolf Putin" and "Russians stand for Ukraine" while the crowd chanted, "Stop war, stop Putin!" and the Ukrainian national anthem was played.
The group have vowed to march again on Saturday and urged New Zealanders to join them.
It comes as the war in Ukraine ramps up with reports of the 'Father Of All Bombs' being dropped.
Reuters report that the Ukrainian Ambassador to the United States, Oksana Markarova, has claimed that Russia used a vacuum bomb during the conflict.
Vacuum bombs are a thermobaric weapon that creates mass destruction by sucking oxygen from the air to create a high-temperature explosion.
The weapons are banned by the Geneva Convention and cause devastating injuries, literally sucking the air from the lungs of anyone nearby and causing a huge shock wave.
