The
NZ Transport Agency (
NZTA; ) is a
New Zealand Crown entity tasked with promoting safe and functional transport by land, including the responsibility for driver and vehicle licensing and investigating rail accidents. It was created on 1 August 2008 by the
Land Transport Management Amendment Act 2008, merging
Transit New Zealand with
Land Transport New Zealand. Its legal name, as established by the Act, is
New Zealand Transport Agency, but it operates as
NZ Transport Agency. Its Maori name,
Waka Kotahi, means "one vessel" and is intended to convey the concept of "travelling together as one".
