Hapū spokesman Koro Nicholas told Morning Report said another death was bound to happen if people kept ignoring the rules.
"We are there to try and stop people from going. Unfortunately, we can't be there 24 hours a day. This death is an unfortunate occurrence, very sorry for the whānau that are involved. There's no anger on our part, there are blatant warning signs there throughout the property.
"We try our best to deter people from going but we've found no matter how high you build the fence or wide you build the fence people will always try to find a way to this very dangerous property."
He said people still continued to visit the falls, even those who had heard about the death.
"Very strange, the pull of social media on these people - it is one of the top 10 things that people try to do locally, and from overseas."
It was raining heavily the day the incident occurred, Nicholas said.
He said there was a very strong social media influence pushing people to head to the falls - including providing information on how to access the falls.
