But Ali pleaded not guilty to a further 15 charges of trafficking in people by means of deception and 16 counts of aiding and abetting a person to unlawfully enter New Zealand, or to stay in the country illegally.
The maximum penalty for people trafficking is 20 years' imprisonment and a $500,000 fine.
Last year, new legislation saw New Zealand's definition of trafficking fall into line with international law as a crime of exploitation rather than just the movement of a victim across borders.
No one has been convicted under the tougher trafficking law.
Human trafficking is defined as modern day slavery and includes the abduction, kidnapping, transporting or transferring of victims for the purposes of sale or exploitation, according to the New Zealand Law Society.
The trial continues this afternoon with Crown prosecutor Luke Clancy and defence lawyer Peter Broad expected to present their opening arguments to the jury.
The trial is expected to last several weeks.
