Mission Statement

SST New Zealand strives to supply adjuvants and spray additives that achieve the following objectives:
- Fulfill unmet market needs
- Exceed the standards for quality, effectiveness and value of its competitors
- Delivered on time
- Supported with expert technical service and advice

SST New Zealand Ltd was incorporated in 2004, however it has been selling adjuvants and spray additives for agriculture, horticulture and turf in New Zealand since 1997. From 1997 to 2003 SST's business in New Zealand was carried out through a joint venture company known as Gullf AG NZ Ltd. That joint venture ceased trading in 2004 and the business was from that point carried out directly under SST NZ Ltd. SST NZ's products are manufactured in Auckland NZ and Melbourne Australia.

SST NZ's parent company was formed in 1991 with the purpose to develop adjuvants and spray additives built on the expertise of its founder John Illingworth. This expertise was acquired through 16 years experience with ICI Australia Specialty Chemicals Group in research and development, sales and marketing of specialty surfactants for agriculture.
