Labour's communications spokeswoman, Clare Curran, has taken her colleague Shane Jones to task for wading into her portfolio area and criticising a Green Party bill to allow exemptions to copyright for the sake of satire.
In the Weekend Herald, Mr Jones said Green MP Gareth Hughes' proposed bill to allow copyrighted work to be used for parody or satire was part of a "Green agenda" of economic vandalism and would endanger jobs by damaging companies' brands.
However, Ms Curran said she did not agree with Mr Jones and his comments were contrary to Labour's general policy on the issue.
She later told the Herald she had contacted Mr Jones.
She said Mr Hughes' Copyright (Parody and Satire) Amendment Bill was in line with Labour's policy.
