State Police Lieutenant Elizabeth Armijo confirmed Bennett's death on Thursday, a day after a helicopter carrying him and five others went down in a mountainous rural area of northern New Mexico.
Obert Gutu, spokesman for the MDC-T opposition party, said the loss of Bennett, a white man who spoke fluent Shona and drew the wrath of former President Robert Mugabe, was tragic. Gutu says Bennett's wife, Heather, also died.
The crash killed five and injured a sixth person aboard. The helicopter went down about 6 p.m. Wednesday near the Colorado state line.
Armijo said no additional information was immediately available about the circumstances of the crash.
