G'day RossS1028,
And a warm welcome to the ODK Forums.

The Parts List for this machine [available as a free download to ODK Subscribers] shows this 'Transfer Wheel' component as an assembly, with a replaceable rubber tyre, P/No 50069.

This part is available here in Oz as a genuine [OEM] Masport item, e.g. from the ODK Shop; around AUD$60. LINK

So it should be available in NZ too, via Masport dealers.

Cheers,
Gadge
