A consortium led by Agria has received more acceptances to its 60-cent-a-share offer for PGG Wrightson.
The consortium is made up of Chinese firms Agria and New Hope, and Ngai Tahu.
It has agreements totalling a 73% stake in the rural services firm.
Investors who have sold will be scaled back, as Agria wants just over 50% of PGG Wrightson.
The offer closes on Saturday.
