She encourages people to give the informal speeches a go because learning a new language need a lot of practice.
It is also not just learning a skill, but something interesting in your daily life to keep your brain alive, she says.
"My students do not have many chances to speak to Chinese people until they can fluently speak it, and to reach this stage needs many years of constantly learning and practicing.
"I want to offer an encouraging occasion to people to practice the language rather than using it to compete.
"I will also support people who have enrolled by helping with their speeches, and the time limit is under three minutes."
Waitsu says it is important to celebrate NZ Chinese Language Week because these days China has become one of the main trading countries with New Zealand and Chinese visitors are one of the major tourism resources.
"There are also many intermarriages with second or third generation history links with Chinese.
"It is a way to highlight Chinese cultural history in New Zealand through the celebration of NZ Chinese Language Week."
