Sperm donor Bill Johnson is back in the United States after disclosing his secret life.
The Alabama-based conservative Christian campaigned against gay marriage before arriving in Christchurch earlier this year where he took a job as long-term recovery manager for Ceres Environmental's local affiliate.
Last weekend, the Herald on Sunday reported Johnson had donated sperm to women in the city without the knowledge of his wife, former beauty queen Kathy.
Three women had become pregnant; six others wanted to.
Ceres Environmental president Troy Garrett, speaking from the company's Minnesota headquarters, said he was aware of the sperm donation allegations.
