Hmmm interesting. The Oneworld planning tool is not giving me that information. It has offered me prices flying with Fiji Airways both CHC-NAN and NAN-LAX.
Frustrating because that is a part of my trip that I thought worked.

Edited to say that the tool is pricing as GLOB not ONE. So that answers that question.

But why am I not allowed to have a stopoever in HEL at the end of my trip?
