"The numbers are consistently increasing. We are putting a lot of time and effort into our website so parents can find out about our city and schools throughout the year.
"That kind of advertisement will help them find out the city is the best place for their children's education.
"Our Korean families are very happy with the schools and are very satisfied with what we are doing for their children."
Mr Yang said most Korean families stayed in the country two to three years but many wanted to stay longer. Fathers usually lived in Korea to earn money while the rest of the family lived in Tauranga.
Pillans Point School principal Matt Simeon said international students were an important part of local schools from both a cultural perspective and also the financial impact on a school.
His school has 14 Korean students and one from Germany. Mr Simeon said the international students had a big impact on local children and together helped build a classroom culture of understanding and diversity.
"They understand the world is bigger than just our school and our city."
Mayor Stuart Crosby said international education was important for the city.
"It does assist in our economy. It has a gross value of over $30 million a year. That often goes back into education.
"From my perspective, it's not about that as such.
"It's about the opportunity for international students to come to our city, experience our city, enjoy our city and get to know our people.
"There's also the other side for our students to have more engagement with students from overseas," he said.
