Hon GRANT ROBERTSON: Decisions we make about our infrastructure can affect us for decades or even centuries.

The document is a step towards a better future. It sets out the challenges we're facing and proposes solutions. Te Waihanga is now asking New Zealanders what they think. Consultation is open for six weeks, and from this feedback a 30-year strategy for New Zealand's infrastructure will be developed and published in September.
