Dairy Women's Network trustee and Waikato dairy farmer Pamela Storey is standing for the Waikato Regional Council.
Judges say decision making on the couple's 244ha (215ha effective) dairy farm 'Tremeer' focuses on profitability while caring for the people, the cows and the environment.
Grant and Karen were announced winners of the Supreme Award at a Ballance Farm Environment Awards (BFEA) ceremony on April 3. They also collected the Ballance Agri-Nutrients - Nutrient Management Award, the LIC Dairy Farm Award, the Hill Laboratories Harvest Award, the Massey University Discovery Award and the Meridian Energy Excellence Award.
With the help of sharemilker Steve Ironmonger they run a 650-cow operation that consistently achieves production above the regional average.
BFEA judges say the excellent condition of the farm and the herd was positive reflection of the couple's commitment "to balance a profitable and sustainable dairy business with being an enjoyable place to work".
Tremeer was originally a sheep farm but Grant and his father started converting it in 1988. Grant and Karen initially sharemilked with Grant's parents Derek and Audrey, before buying the farm in 1997. In 2003 they purchased a neighbouring farm that was also previously owned by the family.
Cow numbers have steadily increased over the years and this season the farm is targeting production of 280,000kg M/S.
BFEA judges were impressed with the couple's extensive use of monitoring and record keeping to constantly monitoring the business and the environment.
Feed efficiency is a key driver and Farm Working Expenses are carefully monitored. A strong focus on energy efficiency helps the business minimise costs and reduce wastage.
Three herd homes are utilised on the farm, with BFEA judges noting the positive impact this has had in creating a good working environment for staff, enhancing animal health and increasing pasture production and utilisation. Feed bunkers are located near the herd homes to reduce machinery requirements.
Water quality is a high priority on Tremeer. Waterways have been fenced since 2002 and an ongoing riparian planting programme is in place. Thousands of native plants have been established in the last ten years and this has led to a significant improvement in birdlife.
BFEA judges say Grant and Karen keep up to date with technology and research advances. The couple have strong links to rural professionals and this helps add value to their business.
Judges also noted the excellent mapping and recording of effluent areas, with major efficiencies gained by testing each paddock for fertiliser requirements.
They praised the couple's 'shared responsibility' approach to staff management, and their commitment to balancing their business careers with community and family life.
Judges say Grant and Karen's business success has helped facilitate their involvement in community activities "and this is highly commended".
A BFEA field day will be held on Tremeer on Wednesday, May 15, 2013.
