THE war over New Zealand's chocolate market has flared up again, with confectionary giants Cadbury and Whittaker's back in court over the trademarking of a name of a block of chocolate.
The stoush between the two companies stems from an application made by Whittaker's in 2010 to register the name "Berry Forest" as a trademark in New Zealand.
The Intellectual Property Office ruled in favour of Whittaker's last year, a finding Cadbury appealed.
Justice Rachel Dunningham is hearing the appeal case, which began this morning at the High Court in Wellington.
Cadbury believes the name "Berry Forest" is too similar to the name of its "Black Forest" chocolate block. The company registered the name as a trademark in 1992.
The case continues.
