ENP:

I am not sure just what your query is, however this may be relevant, a few Australian companies with NZ operations, Westpac is one, do have usable NZ imputation credits. I recall on my Westpac dividend advice this amount being clearly stated, so have a look there.

A thought that does occur to me, is that I think my shares are registered in NZ and certainly have dividends paid in NZ dollars,
where this is not so, this imputation credit may not be shown in the same way.
