Diack is the brother of Laurence Diack who set up Mr and Mrs KiwiSaver with Nick McCorkindale. Before being a KiwiSaver salesman he held customer service positions with the National Bank and WiNZ.

Diack told Good Returns that it was a good thing to get people to save. Many of the people he had signed up didn't know they could join KiwiSaver and getting $1000 from the government was "a good thing".

He had signed up 4000 people to KiwiSaver and had used four different providers.

He says the money was not in the commission he was paid to sign up members but with the trail commission.

His original provider paid a $40 commission and a 15 basis point trail.

He changed providers and worked for Mr and Mrs KiwiSaver after being "fired" by the first provider.

He had a brief flirtation with Grosvenor and worked for SuperLife.

Diack acknowledged there had been complaints against him and he had had run-ins with WiNZ.

The department had reported him to the police more than 15 times and had trespass notices issues against him in Napier and Flaxmere.

The Financial Markets Authority says Diack was engaging in illegal sales activities.

It says besides offering people money to sign up to KiwiSaver he was not providing them with an Investment Statement.

Diack has also failed to comply with the requirement to be registered as a financial services provider under the Financial Service Providers Act which came into force on March 31.

FMA chief executive Sean Hughes said "high pressure or coercive sales techniques are inappropriate for KiwiSaver schemes and residential door-to-door selling of any security is prohibited by the Securities Act."

Hughes said the FMA's actions against Diack's activities should "serve as a warning to other KiwiSaver and financial product providers of their legal responsibility for those acting on their behalf and their moral obligation to protect their customers."

Diack had been censured by the FMA. He says his time as a KiwiSaver salesman was coming to an end anyway and he wasn't making much money out of it.
