The Northern Ireland Police Service is appealing to New Zealand women as part of their investigation into abuse in homes for unmarried mothers and their children.
Between 1922 and 1996 more than 10,000 women and girls were forced to work in the notorious laundries run by nuns.
It's been just over a year since Northern Ireland Police launched an investigation into abuse in Mother and Baby Institutions, workhouses and Magdalene Laundries.
They've spoken to more than 80 people in that time and they now believe there are more victims and witnesses out there.
Those who were adopted from Northern Irish institutions and now live overseas have reported inconsistencies with birth records.
The head of the investigation Detective Superintendent Gary Reid said "many people who may have given birth in these institutions, or who were adopted from them now reside outside of Northern Ireland including countries like New Zealand".

So-called 'fallen women', prostitutes, women who became pregnant out of marriage or as a result of sexual abuse as well as orphans or abused children were sent to these homes and forced to work relentlessly.
Survivors of these institutions have spoken about the horrific abuse, physical and psychological, they suffered at the hands of priests and nuns.
They were forced to change their names when they arrived, and were often coerced into giving up their child.
Northern Ireland Police said it doesn't want people to feel they have to suffer in silence anymore.
"If you believe you were the victim of abuse or other forms of criminality in any of these institutions in Northern Ireland, or know somebody who was, or if you witnessed anything suspicious, please contact us.
"We care about what you have to say, will listen and support you, and will act to keep you and others safe."
