Chiu, 40, said she moved back in 2006 to give birth to her daughter, and these were the worst riots she has seen.
She participated in the mass protest on June 12, but didn't take part in the demonstrations overnight which had resulted in violent clashes.
The protesters, mostly young, wore surgical masks to hide their identities and plastic goggles to ward off pepper spray which police fired sporadically all day, along with tear gas, rubber bullets and bean-bag rounds.
Chiu, a data analyst, lives in the southern part of Hong Kong, about four train stations away from the financial hub, or Admiralty station, where the main protests took place.
"Admiralty station is temporarily closed to stop people from going there, but people are still finding ways to get there," she said.
"Police are doing this so the council can reopen the meeting and forcibly pass the extradition bill."
The Hong Kong Government led by Chief Executive Carrie Lam has said it had no intention of giving in to the protesters' demands of scrapping the proposed law.
The protesters felt the law would undercut local autonomy and end Hong Kong's status as a safe haven for dissidents fleeing the mainland.
Auckland businessman Joe Lam was in Hong Kong last weekend and said the demonstrations were the largest he had ever seen.
"The root of China is very deep for Hong Kong people, and most love our country - China," Lam said.
"We will all proudly tell people we are Chinese, but we do not agree with everything the Chinese Government does."
In the last Census, 222 people living in New Zealand identified with the Hong Kong Chinese ethnic group.
More than nine in 10 lived in the North Island, and two-thirds lived in the Auckland region.
