Paul Cooper
Nutrition Sales Specialist - North Canterbury, Marlborough

Peta Hamilton
Nutrition Sales Specialist - Lower North Island
I was born and bred in Whanganui and grew up on a sheep and beef farm. I have had a passion for farming from a young age. After meeting my husband, Andy, and following him around New Zealand as he chased the high-country sheep and beef farming dream in the South Island, I decided to throw myself into relief milking, calf rearing, and working for LIC, where I found dairy farming really interesting – especially raising quality calves and young stock. I started my journey within the rural retail sector with PGG Wrightson in Lumsden before continuing in the Whanganui PGG Wrightson store after moving back home in 2021. I have three daughters, Quinn, Honor, and Geva, whom I really enjoy spending time with, whether it be driving around the countryside to different horse events, heading to WOW in Wellington, or spending time at the beach. I am an avid sports fan, especially of Netball and Rugby. I help coach a local school netball team and spend most winters on the sideline watching my daughters play. I am looking forward to getting out and about on the farm and getting to know farmers within my region. Read Less
