Age Concern Tauranga chair Deborah Jagger said financial abuse was most prevalent followed by physiological abuse.
"They don't go anywhere because 80 per cent of it would be family members. The issue is these are very clever people that have often been doing it for years and you need to be able to prove that."
The impact could be devastating on the elderly, she said.
"The effects are huge; you see behavioral impacts, you see withdrawal, we sometimes see things like incontinence or lack of eating. Others end up with no money or no power."
It was not okay for anyone to feel unsafe or vulnerable and she urged people to reach out.
"If it is that bad and they are scared, things like documenting and taking photos to substantiate what they are saying is useful. We have a dedicated trained person that takes on any elder abuse cases."
Tauranga Western Bay of Plenty Grey Power president Christina Humphreys said people were often desperate and just wanted someone to talk to.
"A lot come in our door and say it's their children bullying them for their money. One was an 80-year-old lady who had a son that was up to his eyeballs in debt with maxed out credit cards and a mortgage that he wanted her to pay for." These are the things we are hearing. Some of them are just awful ... like a parent that has been plonked in the garage after their children have got all their money."
Grey Power advised people to call Healthline as it was operated 24 hours or Age Concern, she said.
In 2012, the Age Concern elder abuse and neglect prevention service reported a 50 per cent increase in referrals.
