The sum is part of a settlement to compensate the woman for "emotional harm and lost earnings", said the human rights body that represented her.
The case served as a reminder that all workers have the right to freedom from sexual harassment at work, it added.
New Zealand passed a law decriminalising sex work in 2003.
The details of the proceedings, including the identities of those involved, is confidential.
But the settlement announced on Monday was viewed as an important milestone for sex workers' rights.
