Meet the Team

Mainland Minerals Company Information

We pride ourselves on being an innovative company with a great team of staff working to meet the fertiliser needs of our local farmers! Our products and services are being improved and added to all the time, so we know we are offering you the very best fertiliser options possible.

We are truly your local fertiliser company corporate offices or suits here! 

The fine particle fertiliser system was first pioneered by Mainland Minerals, over 20 years ago.  The company was formed in 1988 and operated as a nationwide company, with Dr Tim Jenkins joining in 1998 to establish credible, independent soil testing and fertiliser recommendations.

In 2007 the company was split up regionally, with Mainland Minerals Southern being formed and individually owned by Gavin Keith and Murray Cockburn.

Since then we have gone from strength to strength, make improvements and innovations to our systems, and as part of the Mainland Group, are the third biggest fertiliser supplier in New Zealand!
