New Zealand Customs is to provide support and training for the Fiji Revenue and Customs Authority.
It was being funded through the New Zealand aid programme.
Customs Minister Nicky Wagner said the plan would improve border security with a focus on drug smuggling, money laundering and to stop Fiji being used as a transhipment point.
The plan builds on other projects with Fiji in recent years, including the introduction of detector dogs and leadership training.
New Zealand supports similar border capacity development in Samoa and the Cook Islands.
