If you are interested in Barnyard pellets, they are available in more places than Helensville and Pukekohe, thankfully

That's what we're using at the moment too. I buy the 25kg bags locally in Warkworth, they're available at Falloons in Dairy Flat, and I'm pretty sure at RD1 in Albany and I think at Farmlands and Wrightsons in Wellsford (although that is probably way too far away!) and Lifestyle Animal Supplies in Swanson. They're a pretty common brand so I think the majority of farm supply stores stock them. And, yes Countdown for that emergency 10kg bag over the holidays. Have done that more than once!
