Existing and proposed extension to Gabion seawall protection in Tokelau : environmental impact assessment (EIA)

Abstract

Following Cyclone Ofa, which caused extensive damage to Tokelau in February 1990, a programme of seawall construction was undertaken by the New Zealand Defence Force (NZDF) and Tokelau in the last quarter of 1990. The position and design of the seawalls was based on a report by Maccaferri Gabions New Zealand Ltd prepared in June 1990 by Mr C.C. Brockliss. The initial design concept was to construct seawalls that would provide adequate protection but at the same time have minimal effect on the natural environment. Construction of the seawalls was not completed before the NZDF departed and the Tokelau people continued with the work.
