I dont know there are many substitues for something with desriptors like
"The aroma is characterised by a heady mix of lemon peel and pine needles layered beneath the clean spiciness which typifies this New Zealand alpha selection"
Pine I would think Chinook, but lemon, dunno,
"Used for first addition bittering this hop has no pretence at substitution for noble type. A kettle variety of the highest order Southern Cross imparts a soft bitterness with a subtle resinous quality. The essential oil component is such that it can deliver a delicate balance of citrus and spice when added toward the end of boil. Generally selected for its consistency in mainstream Lagers this hop has also ventured into the craft market as a reliable Brewpub mainstay."
Citrus and spice? Id be looking to blend if I couldnt get hold of any, if you are sold on having this then there arent too many options, from those descriptions, Id blend a few, chinook, citra and a dash of simcoe or something if thats what I were chasing (Still dunno about the lemon though), very much a thumb in the air type thing though you'll agree.
I couldnt find anything in the substitution chart I have either, it's not listed in there.
Cheers and good luck
