NSW Police said in a statement on Tuesday afternoon the human male remains found at Mollymook on Friday belong neither to Ms Caddick nor a man who went missing from Batemans Bay on January 25.

DNA from the remains will now be tested against the missing persons database.

Police are continuing to scour beaches on the NSW south coast for traces of Ms Caddick after her decaying foot was found south of Tathra on February 21.

Additional remains were found at Cunjurong Point on Saturday afternoon and Warrain Beach at Culburra on Sunday morning.

Police said on Monday evening they would forensically examine those remains to determine if they belonged to the 49-year-old Ms Caddick.

Additional remains found by members of the public at Tura Beach on Saturday have been confirmed to come from an animal.

Ms Caddick, who is alleged to have defrauded more than $20 million from investors, vanished the day after corporate watchdog ASIC executed a search warrant at her Dover Heights home on November 11.

Liquidators say the fraudster "meticulously and systematically" deceived those who entrusted millions of investment dollars to her over seven years, then used the money to fund her lavish lifestyle.

NSW Police Assistant Commissioner Mick Willing on Friday told reporters foul play against Ms Caddick was possible but suicide was more likely.
