Valu-Pome'e was previously exempt from the requirement to be licensed. However, after her practicing certificate from the New Zealand Law Society expired in July 2013, she no longer qualified for the exemption to provide immigration advice.
"Mrs Valu-Pome'e provided immigration advice illegally to members of the Tongan community, including a Greymouth family, a couple, and a mother and daughter based in Auckland.
"All of the victims were unlawfully residing in New Zealand when they finished their dealings with Mrs Valu-Pome'e. She didn't successfully obtain a visa for any of them," Albiston said.
"This case serves as a strong reminder the IAA will not tolerate those who provide unlawful New Zealand immigration advice at the expense of vulnerable communities."
The IAA ran a campaign earlier this year to raise awareness among Pacific communities in New Zealand, as well as in Tonga, Samoa and Fiji, that unlawful immigration advice can cause significant stress and problems for visa applicants.
"Anyone seeking immigration advice should use a licensed adviser or someone who is exempt, such as a current New Zealand lawyer," Albiston said.
A register of licensed advisers is available on the IAA website.
The IAA investigates complaints made by the public about unlicensed immigration advice.
Individuals found breaking the law can face up to seven years in prison and a fine of up to $100,000.
"Anyone can talk to the IAA about their experience without their immigration status being affected," Albiston said.
