One of the country's biggest fishing companies made nearly $27,000 in donations to the New Zealand First Foundation, which has been bankrolling the New Zealand First Party.
Records viewed by RNZ show the foundation received a total of $26,950 from seafood giant Talley's and its managing director Sir Peter Talley, between 2017 and 2019.
None of the donations were disclosed because there were four separate amounts, none of which exceeded the threshold at which donor's identities must be made public.
RNZ's In Depth reporters Guyon Espiner and Kate Newton have been investigating, and Guyon Espiner filed this report.
