TRMC president Ewa Fenn said there would be 30 different cultural groups being represented on the day.
"We try and make it bigger, better and brighter each year," she said.
Mrs Fenn said it was important for locals in the Bay to appreciate its growing diversity.
"People are sometimes protective of their own culture in New Zealand but obviously the government allows people from all over the world to come and settle here.
"Our role is to get to know each other, for locals to get to know the newcomers and visa versa so we can understand each other.
"People can come to the festival and see performances from various countries, try the different food and meet people from all over the world and see they are not that much different from themselves.
"By education, understanding and meeting people you can become more familiar and barriers will be broken down."
People will be more understanding and accepting of others, she said.
Cuisines on the day will include Maori and British, as well as food from Japan, Thailand, Africa, Trinidad, Korea, Nepal, India, and Philippines.
