Anyone know any good soil mixes from new zealand?

As the title states, im struggling to find a good soil. My grows have been ok but not good enough and i need to find a really good soil and what kind of ferts go well with it. Any advice?

I posted this in the Organic Fanatics thread a while back .hope its useful !

G day I experimented a bit this summer with growing in pots I tried a hybrid dirt and coco grow using a mix of organic and coco ferts and got a good result as far as that the plants were well grown and healthy but they lacked flavour Here's one of the buds from that grow
then I tried a few plants with various amounts of organic ferts in premium organic potting mix,the one that gave the best results was this one, its was a 60 lt bag off premium organic potting mix with a 600 ml measure of Dynamic lifter and another 600 ml measure of blood and bone mix thoroughly ,this plant is in a 50 lt pot and was feed once with a dose of power feed ,she was planted at the start of January and was a small cutting plant in a 2 lt pot of coco ...real happy with the outcome and can be done using your local hardware store.no frills at all. She stinks to high heaven
