The key topics will be road pricing, new cities development, master planning, integrated urban development at scale and value capture.

"China has built up enormous capability in recent years in infrastructure technology, safety and sustainability," says Stephen Selwood chief executive of Infrastructure NZ.

"Improvements have been made without compromising the speed of decision making or the ability of infrastructure delivery agencies to implement.

"We are very interested to understand how they have been able to achieve this, while at the same time integrating across multiple infrastructure portfolios and aligning development aspirations with public services.

"Each of the three destinations has been far more successful than New Zealand in aligning transport investment with urban development, including capturing the value of development to fund major rapid transit improvements.

"Hong Kong’s MTR is famous for above station redevelopment and operates one of the only self-funding public transport systems in the world.

"Singapore’s infrastructure planning and investment programme is the global benchmark, and we are especially interested in their new road pricing initiative.

"When operational, it will become the world’s first comprehensive road pricing network, allowing variable pricing to optimise traffic flows.

"In addition to understanding how infrastructure and development are aligned and delivered, the delegation will provide an excellent opportunity to strengthen business relations across the countries.

"The delegation will take place over two weeks and be modular, allowing representatives to take part in either the Hong Kong-Singapore leg, or the China leg, or both.

"This will be our largest ever delegation and will complement recent trips to the USA, UK and Canada," Selwood says.
