A Powershop advertisement which showed a zombie being impaled in the head by a screwdriver was amended after complaints about its "sickening" nature.
The advertisement, which ran as a banner across TradeMe, with the slogan "Same Power Different Attitude", showed a zombie holding a ladder with a hammer and screwdriver then falling and impaling the zombie in the head.
The image was continuously shown on the TradeMe website in mid-May.
Two people complained to the Advertising Standards Authority, saying it was inappropriate for general viewing.
One of the complainants found it sickening, even as an adult.
