Known as Tet to the Vietnamese and Seollal to South Koreans, the Lunar New Year is celebrated by many other Asian cultures as well.
In Auckland, the Lunar New Year will be welcomed with prayer, firecrackers, lion dancing and a skyjumping God of Fortune.
Mrs Wong first came to the city as a student in 1988 and decided to settle permanently five years ago with her husband, Vincent, now 53, and children Matthew, 17, and Chloe, 7.
Her parents and sister, who also live in Auckland, will be at Sunday's reunion dinner.
Mrs Wong said Chinese New Year was the one time in the year that reminded her of the importance of her culture.
"The public celebrations, like the lantern festival, show an acceptance in Auckland of what multiculturalism is all about," she said.
"On a personal level, wearing my Chinese costumes, keeping the traditions, Chinese New Year reminds me of my culture and makes me feel important about my culture."
Auckland lawyer Arthur Loo, a locally born Chinese, recalled that Chinese New Year celebrations used to be nonexistent in New Zealand.
"We didn't celebrate so much as a child. The Chinese population in Auckland was so small so any celebration was within the family."
Now, about 175,000 Chinese call New Zealand home.
University of Auckland Professor of Asian Studies Manying Ip said Chinese New Year had become part of New Zealand's cultural landscape.
"Celebrations have gone from what was just something that happened privately within homes to public spaces, with huge participation from non-Asians," said Professor Ip, who is also a trustee of the Asia New Zealand Foundation.
"The Lantern Festival, for example, provides a window to the Chinese culture and the festival, and is one example of how the Chinese New Year experience is being shared today."
Chinese New Year fairs and festivals now take place in venues across Auckland, from the ASB Showgrounds in Greenlane to Vodafone Events Centre in Manukau and to suburbs including Northcote, Whau, Parnell and Remuera.
Massey University sociologist Paul Spoonley said the public Chinese New Year events were important in helping migrants settle in Auckland and sent two messages.
"That you, immigrants, are welcome and the festivals recognise that your culture is important, and they provide something which is familiar.

"Festivals are one of those moments that all New Zealanders, new and old, can come together to celebrate and share.
"The Lantern Festival has become one of Auckland's most important annual events and the participation levels continue to grow, including from non-Chinese communities."
Massey University China specialist Henry Chung said Lunar New Year was regarded as the most important Chinese festival.
"It is traditionally a time to be with family and reunions, and a time when the entire year is assessed and plans for the future year are made," Dr Chung said.
On New Year's Eve, devotees will head to Fo Guang Shan temple for a dharma function to offer prayers.

In the central city, firecrackers and lion dancing at SkyCity will start festivities with a bang.
The God of Fortune, one of the festival's key characters, will descend from the Sky Tower and present guests with hong bao.
"There's considerably more awareness of Chinese New Year and how it is celebrated ... and there is a growing expectation for different communities to hold Chinese New Year celebrations," said Vivien Bridgewater, general manager destination Auckland Tourism, Events and Economic Development.
She said Ateed worked closely with various community and business organisations to ensure their celebrations, like the Lantern Festival, were as authentic as possible.
For the first time this year, the Lantern Festival - which traditionally marks the end of Chinese New Year celebrations - will be held at the Auckland Domain instead of Albert Park.
