Justice Minister Amy Adams is attending an international law conference in London alongside Justice Ministers and Attorney Generals from around the world this week.
The Global Law Summit, held from February 23 to 25, is a collaboration between the British Government, the City of London and the legal sector to mark the sealing of Magna Carta by King John at Runnymede in 1215.
While in London, Ms Adams will meet with key ministers in the British Government, including Home Secretary Theresa May, and Lord Chancellor and Secretary of State for Justice Chris Grayling.
Ms Adams will also speak as part of a panel on the principles of Magna Carta.
Her speech will centre on New Zealand's experience in creating a more efficient justice system by modernising courts including speeding up justice by making better use of technology.
