SP Blinds was founded in 1961 on Karangahape Rd as Sunproof Blinds by a Jewish family. It passed through three more owners and was situated in the old Kent Street bakery in Newmarket when it was acquired in 1995 by Erhard and Ann Hein.
Erhard and Ann owned the business for nearly a decade and employed 18 people manufacturing roller, roman and Austrian blinds. They also supplied rattan and woven timber blinds and offered spray painted finishes. They distributed blinds all over NZ to both commercial and residential projects. Erhard was particularly well known as the expert for supplying and fitting skylight blinds when no-one else would attempt them.
