The 4-tooth Finn ewe produced a mini flock of her own last month, delivering six healthy lambs.
This followed sextuplets the year before, only five of which were born alive. As a hogget, she had produced twins.
Daniel Wheeler, of Broomfield near Amberley, said the whole family was ''doing well''.
However, to give them all a good start in life, three of the lambs were taken from mum after 48 hours and were now being bottle-fed.
''She is a real mother hen. She was rarely more than a metre away from the lambs,'' he said.
Mr Wheeler pregnancy-scans sheep throughout the South Island under the name of Daniel Wheeler Livestock and he breeds pure Finn ewe. He had scanned the ewe as being in lamb with six lambs.
He has one of the last Finn flocks in the country. There are around 400 Finns in total in New Zealand.
''There is only a handful of purebred Finns left in the country, and I have 100 of them,'' he said.
Native to Finland, the breed is one of several Northern European short-tailed sheep breeds.
It was notable for its high incidence of multiple births. It was common for a Finn ewe to have three to five lambs.
The lambs were often small, but were vigorous at birth and grew well.
''They are very good for lifestyle blocks, as friendly as, and very productive,'' Mr Wheeler said.
