Hi Sarah,
I don't quite understand what you mean with a "mentor", and a practicum that isn't clinical, but for new Zealand - here are some organisations, where you could ask for help:
Universities/ Physiotherapy Schools:
1) www.otago.ac.nz
2) www.aut.ac.nz
Physiotherapy Board: www.physioboard.org.nz
NZ Society of Physiotherapists: www.physiotherapy.org.nz
Hope this helps,
kind regards,
Fyzzio
