Jensen family enquiry.

Would anyone be researching the Jensen family, Peter Jensen, his wife Louise Fredrikson, and their family, Larsine, Christine, Anton, and Jens, who immigrated to New Zealand in 1873, aboard the ship "Punjaub"? My grandmother was from this family, but she was born in New Zealand in 1886. I would be interested to know more about the life of the family before they immigrated to NZ, but anything at all would be greatly appreciated. Thanks, Allan.
