The Serious Fraud Office has laid charges relating to two donations made to the National Party - one in 2017 and one in 2018 - both of $100,000.
Court documents obtained by RNZ show charges have been laid against four people over the donations in June 2017 and June 2018.
The documents show three defendants each face two joint charges of deception.
The charge sheet said they used a "fraudulent trick or device" to break up the 2018 donation into sums less than $15,000 which were then transferred into the bank accounts of eight different people, before being paid into a National Party electorate account.
A fourth person charged over the 2018 donation is also charged with providing misleading information to the SFO.
