The historic site, once used by amateur and professional photographers to capture the beauty of Rarotonga, is now covered in tagging.
Images of the defaced rock formation uploaded online by Darryl Thorburn has generated an outcry from the public to deter this behaviour.
The site has been targeted by taggers over the years however the issue seems to be out of hand now.
Some of the spray painted messages seem to be in memory of a deceased friend, however the act is being called ‘disgraceful’ by many online commentators.
“Sad to see a special favourite place for me and many others trashed by some goon with a can of paint,” wrote Thorburn on his Facebook page to accompany the images of the defaced Black Rock site.
“These beautiful ancient lava flows have seen so much and to receive this treatment by what can only be described as a stupid disrespectful act of crass vandalism saddens my soul.”
His post on Facebook not only caused many to share their views on the vandalised site but also offer some solutions to how to remove the paint.
“If they are grieving that person and the Rock is a significant part of the deceased persons past life – put a small plaque down, not graffiti – idiots,” wrote one man.
“I'm appalled at the graffiti around,” wrote one woman.
“When I moved here 6 years ago the Sheraton had one or two tags, now it is covered – such a shame!”
Detective Inspector Areumu Ingaua says that if found, those responsible for this unlawful act will be prosecuted for wilful damage.
Ingaua says the police take matters like this seriously and as the site is on Crown land and one that is a tourist attraction and so its value is greater than $50 – a term of three years in prison could be imposed on the perpetrators.
Police will be looking into the matter further.
