A group of businesses and organisations wants the Government to step in to stop postage price rises.

From next month, New Zealand Post is hiking prices for bulk mail customers by 30 percent, a total increase of 100 percent in the last five years.

Thirteen groups signed a letter to the Government including Grey Power, the Magazine Publishers Association and the Rural Advocacy Network.

Spokesperson Maddison Burgess-Smith told Mike Hosking the increase is out of line with the rest of the world.

She says in the same period, Australia is up 20 percent, Canada seven percent, and the UK 33 percent so the Government needs to have a transparent conversation.
