The closing of the Kaikoura road, due to last November's earthquake, caused major logistic problems in moving produce up and down the country. And then we have Auckland, where congestion makes it difficult for anyone to get anywhere, never mind get produce to market.
This spring, Southland hasn't suffered the wet weather inflicted on the rest of the country, and its produce - potatoes, carrots, and parsnips - was sold all around the country and beyond; New Zealand's roads were what allowed that to happen, and ensured the rest of the country could still get their veges.
The growth of the primary sector, particularly in logging and horticulture, is putting stress on the road and rail networks just to keep the existing ones operational.
Then, on top of that, there is the urgent needs to expand these networks to link provincial communities, and ease urban congestion.
Both the old and new Government had and have plans to address the critical need for efficient infrastructure.
The Government's billion dollars for regional development is an excellent commitment to infrastructure, and their other plans will alleviate some of the existing congestion.
This is urgently needed; the lack of effective infrastructure in New Zealand will be one of the major impediments to our economy's continued growth.
