A 64-year-old man who is believed to have gone missing with his 11-year-old stepson is being urged to contact police to reassure them that both are okay.
John Beckenridge is thought to be with his stepson Michael Zhao-Beckenridge, known as Mike, who has been missing since Friday.
They were seenon Monday when a farmer contacted police to say he'd seen the pair in remote bush in the Slope Point area in the Catlins.
Detective Sergeant Mark McCloy of Invercargill police said Mr Beckenridge may have grievances about a recent Family Court decision in relation to a parenting order.
"John can call me via 03 471 4800 at any stage and talk with me personally about his situation," Mr McCloy said.
"We understand that John and Mike have a good relationship so we are keen to work to resolve this."
Mr McCloy said it appeared they were living rough in remote places, and with cooler weather approaching police were concerned for their welfare.
"We continue to ask members of the public who may have seen Mike or John to contact us immediately. We also would like to hear from anyone who has information that might help us locate them."
