A concession from the Prime Minister that the country may have too many ports.
The drawn out and often acrimonious Auckland port dispute has spawned calls for the number of ports to be culled.
John Key's giving some thought to suggestions we're overloaded in the unloading business, and he says the Productivity Commissioner is looking at the overall structure.
"In the end the truth of it is if we have too many ports then they won't be financially viable and some will close," he told Newstalk ZB's Mike Hosking.
Mr Key says Ports of Auckland is losing business to Tauranga because Tauranga is more efficient.
