The witness known as Ms CU spoke on behalf of her niece, who was 15-years-old at the time of the abuse.
She explained the Tongan society is very hierarchical, saying that ministers, priests and nuns elevate in both status and authority because of the godly factor.
"They are a representation of God on Earth," Ms CU said.
It was at Ms CU's family reunion that took place in New Zealand where the priest met her niece, who had travelled from Tonga for it.
