Lovise & Amalie Andersen - emigrated NZ 1872

My great-grandmother Julia Andersen emigrated to NZ in 1872 on the ship. Hovding, together with her two younger sisters Lovise ( aged 17) and Amalie (aged 16). They originally came from Eidskog but saiied from Kristiana. After arrival they went to Norsewood. Julia then married a Scot, Robert Robertson, and went to live in Ormond, near Gisborne. However i have no idea what happened to Lovise or Amalie. Does anyone recognise those names as possible family members?
