Family and friends helped with the search and the social media campaign to find her reached thousands of people online.
Hundreds of messages flooded onto her husband Stephen's Facebook page after he appealed for information earlier this week.
However, shortly after, a family friend posted a message on the thread with a message from Stephen.
"It is with deepest sorrow that today I have received the news that my beloved Tanya has passed away," it read.
"I'd like to thank everyone involved in the search, and for your prayers and support."
Tributes then poured in for the mother.
One of the family's friends posed that Laws was a "beautiful, kind, loving person and my heart breaks just thinking about what you and your beautiful children must be going through".
Another wrote: "Tanya was an amazing person she had the biggest heart and would always make you feel so wanted, with her big smile and happy and chatty self."
"Heartbreaking. Tanya was such a vivacious and warm person who had an impact on everyone she met," wrote another.
Ms Laws' sister also set up a Facebook page to aid the search effort and shared the heartbreaking news, mourning her "beautiful angel".
"Our beautiful sister, daughter, wife, mother was found today," she wrote.
"She has passed on into God's hands, she was our beautiful angel sent to us for a short time.
"Rest my beautiful sister. Half of me has gone away with you my love."
NSW Police thanked the public for their search efforts.
