"People we didn't even know supported us. We didn't have family here... but we felt like we had family," Kaur said.
Today, at eight months pregnant, her son and father were with her, her husband and her daughter, Avkeerat Kaur.
The family is excited for the baby expected next month who will be born with the black passport.
"Just in time," she said.
But unlike Kaur, Apinya Forrest did not move here by choice, moving here with her family when she was 11.
Born in Thailand, she moved with her family to South Africa and then New Zealand as her parents decided it was the best place for her and her siblings to grow up.
Although it has taken 20 years for her to officially become a citizen, she had considered New Zealand home for a long time.
Her Māori partner and their son joined her as she celebrated the day.
Whangamarino School livened the Council Chambers and performed an energetic poi and a haka that had the ground trembling.
Rotorua mayor Steve Chadwick opened the ceremony with a mention of the vigil two weeks ago to support the Muslim community following the Christchurch terror attack on two mosques on March 15.
She extended an invite for all to share their stories and journeys to New Zealand.
She said it was important to "colour our understanding of what we as New Zealanders take for granted... being citizens by birth".
Each family was given a seedling to "put their roots down" in Rotorua.
The next citizenship ceremony will be on May 6.
