Hi there! Please note, I won't offer recommendations or opinions on other NZ Harp Teachers - if you are looking for a list of teachers or harp makers, you can either search on the NZ Harp Society website or my other NZ/Australia website 
www.harpsdownunder.com
Also - I don't currently own a pedal harp, they are in short supply here in NZ, so I can't help you locate one for your tour or personal use while here in NZ - sorry!!
