Justice Minister Andrew Little has said he is considering looking into changes to the way political parties are funded, and areas such as donation transparency could be part of the discussion.
Little said on Tuesday there was "natural concern" around the levels of transparency of how parties were funded and whether New Zealand's laws provided enough protection and transparency.
"I think there is scope for debate and I suspect we will have one."
The issue has been raised following allegations by Jami-Lee Ross against his former National Party and leader Simon Bridges over party donations. Police are investigating.
Ross last week released a secretly recorded conversation between himself and Bridges discussing a donation of $100,000 to National.
None of the information Ross has released so far appears to show any wrong-doing on the part of National or Bridges but has raised questions about transparency.
