Defence Minister Wayne Mapp said New Zealand would continue to have a relationship with Bamiyan well after the transition to local rule in 2014.
His comments came after meeting Britain's special envoy to Pakistan and Afghanistan, Mark Sedwill.
New Zealand's provincial reconstruction team is based in Bamiyan and by 2014 will move to a civilian development force.
Dr Mapp said Mr Sedwill had been looking for "an understanding that New Zealand's interest didn't just end with 2014" when control of security will return to local forces.
He said the most important thing New Zealand wanted to do after 2014 was to build economic capability and strengthen governance, especially in the justice area.
