He was impressed with the huge piles of logs stacked at Northport awaiting export, but said it was a shame that the raw logs were being exported for other countries to get the added value of processing them.
Mr Cunliffe said the policy would see firms processing more of Northland's logs in the region, which would in turn create more jobs.
"Northland has historically had high unemployment (it's around 9.1 per cent, the highest in the country) and I think we can get that rate down, with forestry, and wood processing," he said. "It will lead to more processing, adding more value, closer to where the trees are grown."
Mr Cunliffe said Labour would also introduce a ports strategy that would help get the most out of Northport - the country's deepest port. The port may look at expanding into a container port.
Part of that would be ensuring that a rail line was connected to the port.
