Karen,
I'm pretty sure that New Zealand is the same as here in Australia in that levels are measured differently from the US. Most measurements you'll read here are in pg/mL.

You'll probably need to convert your path results from our pmol/L to pg/mL

Easy conversion here -

1st paragraph - Vitamin B12 – Reference Range Level Set too Low - from MTHFR Au.

I buy mine from iHerb in the States and I've never found it here in my area in Au.. It's usually measured in mcg so I buy the 5000mcg and break it in half or quarters. I just do that to keep costs down especially with our low dollar at present.
