Looking for Stoop and Fineletter Migration to Otago Gold Fields IN Early 1860s

Hi,
James STOOP and Hannah FINELETTER came to the Otago goldfields from the Victorian goldfields in the early 1860s. I suspect they came together and may even have come as Mr and Mrs Stoop. Hannah would have had one child, Sarah Ann, born 1858, with her and possibly another, William Thomas, born1854.
Iwould be grateful for any help on their arrival or time in Otago before they moved on to the Westlanf field in the late 1860s.
Regards,
