There's disappointment a report on the economic relationship between New Zealand and Australia doesn't make a firm recommendation on the issue of double taxation.
The Strengthening Trans-Tasman Economic Relations report was carried out by the Productivity Commissions of both countries.
Currently, companies operating in both countries have their profits taxed twice, since neither recognises the other's systems for offsetting tax credits.
Australia New Zealand Leadership Forum co-chair Jonathan Ling says the report basically passes the issue onto both governments.
"Certainly I think, now that the Productivity Commission report process is over that I certainly implore both the New Zealand Government and the Australian Government to make a favourable decision on this."
