Hundreds of people are expected to gather in Christchurch's Victoria Square on Saturday afternoon for a march against racism.

The event, Together Against Racism, was inspired by Christchurch mosque shootings on March 15. Fifty-one people lost thier lives when an alleged white supremacist gunned down worshippers as they prayed.

March co-organiser Josephine Varghese says at least 200 people are expected to attend.

"I think close to 1000 people have said they're interested," she told Newshub.

The event kicks-off at 1pm. Attendees will gather at Victoria Square and march to the Bridge of Remembrance.

"We [need] to fight at every single level - even micro levels, micro-aggressions... or the history of colonisation."

Eight people are expected to speak, including Kiwi-Iranian journalist Donna Miles-Mojab.

"We're trying to get a good representation of the community," said Varghese.

"We as a community have to embrace diversity rather than fear it", said co-organiser Brian Turner.
