There will be a range of food stalls including many ethnic dishes, as well as art and crafts stations, information stalls and children's entertainment such as pony rides, face painting, henna hand painting and a bouncy castle.
People are encouraged to bring a blanket or chairs and enjoy the day.
At noon a Parade of Nations will be held, which is an annual highlight where the public are invited to parade under a flag representing their home country.
"Over 20 different nations will be represented with their flags and maybe national costume," Fenn said.
She said in previous years the event had attracted between 3000 and 5000 people.
"It is a platform for people to learn about everyone else living in the city, all the other cultures."
'Give nothing to racism' is the theme of the day, in recognition of Race Relations Day, which was on March 21, as well as the New Zealand Human Rights' Commission's campaign of the same name.
Fenn said racism was not something migrants in Tauranga complained of often, but it was sometimes suspected when they struggled to find jobs.
"They always wonder if one reason is because they are not a Kiwi."
