A group of companies holding trademarks to "ShowMe" and "Show TV" say they are upset by Telecom’s new brand, ShowmeTV.
Telecom has not officially launched its “high-quality” Internet TV service but released its logo on Friday.
However, a marketing company, Show TV, and its associated online retailer ShowMe, say the logos are confusing.
A spokesman for the group of companies, Darryl Clarke, says they are taking legal advice over next steps.
Mr Clarke says the companies have been receiving phone calls and enquiries from people who are genuinely confused about Telecom’s new venture and ShowMe and Show TV.
“It has been distressing over the weekend for our entire management team as we watch Telecom move in on our well-established brands.
"If you look at our Show TV and ShowMe trademarks alongside Telecom’s proposed ShowmeTV logo, it's extremely confusing and raises serious questions about any intellectual property and branding advice Telecom has received on this project."
Show TV promotes its branded product through TV, online and at consumer shows and expos and its parent company Southern Cross Promotions owns the registered trademark “Show TV."
Show TV owns half of ShowMe – which sells the Show TV branded product. Show TV owns the trademark “ShowMe.”
