Marie Olsdatter

Marie was the younger sister of Frederikke Olava Olsen. Olava's sisters Karen and Caroline emigrated to New Zealand in the 1870s. Caroline passed away in November 1896, shortly after marrying Emil Pasche (also from Norway). A family photo has Olava and two of her sisters, one of which is Karen and we had though that the other one was Caroline, but as the photo was taken c1904 this could not be the case. We have not been able to track down any arrival of Marie in NZ so suspect she may have been married when she arrived here. Can anyone find if Marie was married in Norway and if so who to so we can then do further reseach at this end. Also we think their brother Hans Jacob Olsen may have emigrated here but again have not been able to track down his arrival - are there emigration erecords for those coming to NZ?
