Opponents of the controversial Trans Pacific Partnership trade deal are keeping it in the public eye.

About 100 people protested the 12-nation agreement in central Dunedin on Saturday.

Rally organisers are urging residents to lobby politicians about the TPP, with it likely to be an election issue next year.
