of three joint buildings still stand today on the lower reaches of the street, below the SaveMart Building, which was the Kempthorne Prosser laboratory from 1900 until the 1960s. Directly opposite the former laboratories is the office that Kempthorne Prosser occupied during the 1970s, built to replace the earlier structures (31 Stafford Street). The Burnside Chemical Works in Kaikorai Valley Road, Dunedin was the first Kempthorne Prosser factory to be opened in 1881. It operated until 1962, when it was sold to Dominion Fertiliser Ltd, and has since been demolished, however, one small building which functioned as the Men's Dining room still stands. The second plant, the Westfield Chemical Works in Bell Avenue, Otahuhu, Auckland, operated from 1887. It was partially demolished and converted for new use in the 1990s. The main building still stands. The Hornby Chemical Works in Hornby, Christchurch, was opened in 1922, and the Wanganui Chemical Works, Brunswick Road, Aramoho, was opened in 1926. Both are still used by Ravensdown Fertiliser. Kempthorne Prosser also had non-factory buildings in three main centres. Offices in Albert Street, Auckland, were occupied by the company until 1973 (the building was demolished in 1982).

There were further premises at number 132 High Street, Christchurch. The High St premises were to be demolished in 1987.
