Orcon is severing its ties with internet entrepreneur and aspiring political player Kim Dotcom for fear of "running foul" of electoral laws.
Dotcom, who Orcon boss Greg McAlister said wasn't "everyone' cup of tea", featured in ads pushing the company's internet services.
The company today said it was its most "successful campaign to date" but it was now coming to an end.
Orcon said last November its sales jumped 70 per cent in the month after the ads launched.
"We've seen very strong results for the business", McAlister said today.
