A woman who fell to her death while climbing a popular cliff face in the Coromandel has been identified as a 28-year-old United States citizen.

Emergency services were called to Castle Rock near Whitianga just before 10.30am yesterday after reports of a climbing incident.

One woman died at the scene. The deceased is believed to be a 28-year-old United States citizen who was living in New Zealand.

Waikato Police are working closely with the United States Consulate, who are in contact with the woman's family and the Coroner's office. A full post-mortem will be conducted on Tuesday.

Inquiries are ongoing to understand the circumstances of the woman's death.

Stuff reported that the woman was rock climbing with a friend and fell up to 120m.

Her climbing partner then hurried to raise the alarm.

"As a result of that fall she has sustained non-survivable injuries and has sadly passed away," eastern Waikato Detective Chris Smith told Stuff.

Her body was walked out of the bush with the help of Search and Rescue teams.

Smith said police were still making inquiries to ascertain the woman's level of climbing experience.

Kuaotunu Land SAR, Coromandel Fire Rescue, St John Ambulance and the Westpac Rescue Helicopter attended the incident.

Castle Rock is a 525m high mountain which is popular with rock climbers.

Earlier this year the body of Shannon Earle Makowharemahihi was found at the bottom of Castle Rock.

The 37-year-old local man's body was found in dense bush in the area around Castle Rock on June 23, after he had been missing for three weeks.

Mako was last seen on June 1, and was reported missing on June 9. His vehicle was located on June 12 in the area of Castle Rock.

Mako was a recreational climber who was very comfortable in the bush environment.

The cause of his death is the subject of a coronial inquiry.
