"At the same time as our rail lines decline, the pressure on our roads intensifies. This will get worse, as the government is now considering allowing even more monster-size trucks on our roads.
"To ease pressure on Auckland infrastructure the government should be maintaining our national road and rail networks to the highest standards, and providing incentives for businesses to relocate from Auckland to places like Dargaville, Timaru and Oamaru.
"Most of New Zealand's export income derives from provincial New Zealand, but you wouldn't think this was the case under National. They are fixated on Auckland and its problems at the expense of the rest of New Zealand."
Mr Peters also asked what had become of National's by-election promises last year in terms of roads and bridges in the region. Those promises had included two-laning 10 one-lane bridges, but so far the government had only budgeted for the ones at Matakohe, Taipa and Kaeo.
"Given these promises were made to catch votes, and the media were called to announce the government's magnanimity, the failure to follow through is a breach of trust," he said.
"National has gone back to its old ways, and is thumbing its nose at Northland. The bridges were costed at $69 million, so where did that funding go? It's not a matter of whether everyone agreed with the need for two-laning; it's that Northlanders should be able to have faith in the government of the day.
"As Columbus tripped across the Americas, so too did Mr Key and Mr Joyce discover Northland in March last year - and the rest of regional New Zealand soon after - but it appears that's as far as it goes.
"Northland is waiting for the full set of promises - 10 two-lane bridges, superfast broadband rollout, taxpayer-funded cell phone coverage and the Puhoi to Wellsford highway."
