"These have been suggested as potential models for the Justice and emergency precinct in Christchurch," the spokesman said. "He will also look at a large urban renewal project in Los Angeles to understand if there are lessons for the rebuild of Christchurch."
In Los Angeles, Mr Brownlee will meet and thank personally the "first responders" who were involved in the search and rescue work following the deadly February 2011 quake.
"A significant theme of his trip will be the future of transportation systems, which are increasingly being integrated with technology," Mr Brownlee's spokesman said.
"He will visit the Port of Los Angeles, the largest sea port for New Zealand goods entering the United States, and will discuss advances in passenger and freight transport separation in major transport networks."
Mr Brownlee will also look at the future of cars, investigating innovations relating to electrically propelled cars and developments of "driverless" cars.
He will visit the Boeing factory in Seattle to view the new "Dreamliner" 787, soon to join the Air New Zealand fleet.
New Zealand Trade and Enterprise was working to leverage the Government's support of Team New Zealand, and showcase New Zealand's industry to the world, the spokesman said.
"He will support these activities and meet with high level business contacts - both New Zealand businesspeople visiting the United States, and US-based businesspeople."
