Pacific Forum Trade Ministers meet in Fiji next week to discuss a range of regional issues.
New Zealand's Trade Minister Jim Sutton says issues for both Pacific countries and outside the region will be debated.
Of particular interest is the relationship the PICTA or Pacific Island Country Trade Agreement nations have with the European Union.
New Zealand and Australia are outside the PICTA agreement but have rights through PACER - Pacific Area Closer Economic Relations.
Mr Sutton says New Zealand would want to know if PICTA countries were giving EU nations preferential treatment.
