The aim was to learn how local Maori and early missionaries related. Mr Duckworth said Christianity caught on quickly within Maoridom.
"In the end, Christianity was primarily spread from Maori to Maori."
It was no surprise Maori hooked on to Christianity in the early 1800s, he said.
"There was some sort of relief from some of the slavery and some of the warfare. The message of reconciliation was welcomed in what could be quite a brutal life."
But as European settlers began to confiscate land, it made it tough for Maori to buy into Christian concepts. Mr Duckworth said some missionaries continued to stand up for Maori much to the annoyance of Pakeha settlers.
"Often it was the missionaries who advocated for Maori about how they ended up being adversely affected by colonisation.
"We are telling their story, good and bad, because we have to own the story, good and bad."
Nga Tawa student Eden Aschebrosc said the trip had been a great way to meet new people.
"I learned a lot of stuff we didn't learn in school ... it's more personal," she said.
