Anyone know where in Auckland (Manukau) I can buy Fenugreek leaves not seeds? Are they known as anything else? What are Curry Leaves, would they be the same thing???

OH has been trying out various online curry base recipes (curryhouse.co.uk, cuzza.com and jamieoliver.com), but the next stage of making up the various curries need fenugreek - we've been doing without and the results are getting better with each attempt he makes. I shan't be in need of a good Indian take-away soon
