Police investigating a double-stabbing at a Grey Lynn dairy want help identifying a second man they think could help.
A mother and son were brutally stabbed at their family dairy on Great North Rd around 7:15pm on Tuesday.

A man jumped over the counter and attacked the man in his 30s - he has four stab wounds, including two to the abdomen.
His lung and small intestine is ruptured, and he could be in hospital up to a month.
When the man's 62-year-old mother rushed to help him, she was stabbed in the stomach - though her husband says she is likely to be released from hospital today.
A 16-year-old is police custody, and has also undergone surgery.
But police believe there may be up to two accomplices - and want to find the man pictured immediately.
The family has owned the Hylite Dairy 15 years, and say they're still in shock.
