The search for evidence at the former home of missing Sydney woman Lynette Dawson is continuing with no major breakthrough on the second day of digging.
Ms Dawson was 33 when she disappeared from the northern beaches in 1982 leaving behind two daughters.
Investigators started a hand dig on Wednesday at Ms Dawson's old Bayview home where she was living with her husband Chris Dawson - who has long been a suspect in the case.
The former Newtown Jets rugby league player denies any involvement in his wife's disappearance.
The second day of searching turned up no major clues or pieces of suspected evidence, a police spokeswoman told AAP on Thursday.
"We will go until we hit rock," Homicide Squad Commander Detective Superintendent Scott Cook said on Wednesday.
Ms Dawson's niece, Renee Simms, said it has been "incredibly intense" since the fresh search began.
"We're just taking it day-by-day," she told the Nine Network on Thursday.
"We're not going to get too hopeful because we've been in a similar position before and nothing's come of it but it is there under the surface."
Ms Simms said the family has generally accepted that Ms Dawson is dead so finding her remains would be a "good thing".
"Because we could finally put her to rest," she said.
It's expected police will be at the home for four more days.
