Ms Mitchell has been deeply traumatised by the loss of her friend. She said she tried to pull her from the crocodile's jaws but was not strong enough, so had to run to a nearby business to get help.
The attack took place in an area well known for its crocodiles and has reignited debate about how best to manage public safety.
A search of the beach and nearby waterways failed to find any trace of Ms Waldron.
Speaking from her Tauranga home yesterday, Ms Waldron's mother Heather Waldron said she and her family were still trying to come to terms with the tragedy.
"It's difficult to put into words" how they we're all feeling, she told the Bay of Plenty Times.
Ms Waldron, who lived in Australia for 26 years, was a professional photographer and a hard worker, her mother said.
"She was a free-spirited person and wonderful daughter who was loved by everyone."
