Khimich has just spent three months in New Zealand overseeing expansion plans while living on his $30 million super yacht Thalia. "Mikhail pays a lot of attention and a lot of time on this project."
Documents released under the Official Information Act show Khimich's advisers promised the bottling facility would create job opportunities, export earnings and benefit New Zealand's relationship with Russia.
The Overseas Investment Office refused to release background information about Khimich, saying it accepted he and other Russian executives were of good character.
Khimich made billions of dollars through oil and gas interests after the breakup of the former USSR. Kirichuk said his boss had no criminal history and paid taxes.
"He is a very generous man. He could have gone to Australia or the Pacific Islands to invest his money, but he came here."
Khimich has two further applications pending with the OIO to increase his investments in New Zealand companies. Other expansion plans at the Waiwera Thermal Resort include a five-star restaurant and a home for Khimich.
Last week, residents of a camping ground affected by the development, including a 90-year-old war veteran, were evicted to make way for the restaurant. Camp ground manager James Schwartz said those ousted were rehoused in units.
Khimich bought the Waiwera thermal resort and the associated camping ground in late 2010 for $10m, according to property records. He owns a 60 per cent share and previous owner John St Clair Brown owns 40 per cent.
