Key documents about a mysterious foundation loaning money to New Zealand First have been leaked to RNZ detailing why the New Zealand First Foundation was set up, how it would operate and who knew about the idea from the outset.
The documents show Winston Peters, who has tried to distance himself from the foundation, was at a NZ First board meeting in March 2017 where the board agreed to the concept of establishing the foundation.
Another document details how the foundation will operate and talks about seeking donors who would then be offered a "tiered donation structure with benefits adhering to each tier".
Guyon Espiner has been investigating and joins Lisa Owen in the studio.
