Risk factors for gambling participation among mothers included alcohol consumption, being a victim or perpetrator of verbal aggression, and increased deprivation levels.
Dr Maria Bellringer, lead author of the report and Associate Director of AUT's Gambling and Addictions Research Centre, said mothers' gambling behaviours influenced those of their children.
"Adult education and public health campaigns are vital to stem the negative effects of gambling and its transfer across generations," Bellringer said.
Dr El-Shadan Tautolo, Director of the PIF Study, said the data highlighted the need to better support Pasifika mothers, particularly those recently settled in New Zealand.
"We need to put measures in place to support people to retain or strengthen their Pasifika culture while building a sense of connection to New Zealand culture and society," Tautolo said.
He said he was mindful of the intergenerational implications across families and, as the data is collected from a large cluster of essentially Pacific family units.
Tautolo said the consequences for the wider Pacific community could be enormous.
"Clearly there needs to be a comprehensive strategy to tackle problematic gambling and related harms for Pacific people."
"We know that bullying and gang involvement are risk factors for gambling," he said.
