Tenders close on September 16.
The silos haven't been used since about 2004. Golden Bay Cement Company held the original lease on the silos for 10 years from September 1953, and that lease was renewed for another 21 years in 1963.
The cement company signed a further lease in 1984, but five years later it transferred to a trio of businessmen. In April 1995 it was leased to Milburn NZ Ltd for 10 years but in August 2004 the lease was surrendered.
Since that time the silos have been owned by Colmar Holdings, Quay Infrastructure and then River City Port before coming under Whanganui District Council Holdings control in 2010.
Holdings manages and oversees the council's commercial assets, advises on new investment opportunities and on the strategic management of those assets.
