The helicopter went down in the Marondera rural area, roughly 70km (43 miles) from Harare, around 17:00 local time (15:00 GMT) on Wednesday evening, police said. All six people on board died, including two pilots, according to government officials.
Family spokesperson Herbert Chivayo confirmed the deaths to the state broadcaster ZBC, saying the family was devastated by the tragedy.
ZBC reported that Chivayo and his wife were returning from Gandami in Chikomba, where they were building a rural home, when the helicopter crashed at Kudenga Farm about 40 minutes after take-off.
Chivayo was a well-known figure in Zimbabwe for his lavish lifestyle, close ties to some African presidents, and a series of lucrative government contracts that had repeatedly drawn scrutiny. He had denied allegations of wrongdoing linked to his business dealings.
The cause of the crash is not yet known. Police spokesperson Commissioner Paul Nyathi said investigations were under way, and emergency services were sent to the scene on Wednesday evening. Authorities have not immediately identified all of the deceased.
