The inability to conduct an in-country visit limited the data collection to desktop research only. Accordingly, no numerical assessment has been made and the risk observations are based on ship traffic patterns and existing charts. This risk assessment is part of the continuing programme of Pacific regional hydrographic risk assessments being conducted by LINZ, supported by the Ministry of Foreign Affairs and Trade (MFAT), which is intended to cover the extent of New Zealand’s area of charting responsibility. This assessment follows other published risk assessments of Vanuatu, the Cook Islands, Tonga, Niue and Samoa, which are available from the International Hydrographic Organization website at this link. The intent of these assessments, has been to conduct them using the same methodology, in order to provide participating Governments with consistent and comparable information that will assist them and other supporting aid agencies, to make informed decisions in relation to investment in hydrographic work, to provide economic benefit and improve safety of navigation. This aim has not been fully achieved in this brief assessment. 1 This report utilises aspects of LINZ Risk Methodology: South West Pacific Regional Hydrography Programme – Marico Marine Report No. 12NZ246, Issue 3 - February 2013, as further developed by later risk assessments.

It has a total land area of approximately 12km2 but an EEZ of 318,990km2. Tokelau is located in the southern Pacific Ocean between latitude 8° and 10° South and longitude 171° and 173° West. Situated mid- way between Hawaii and New Zealand, Tokelau is approximately 480km north of Samoa. 0.2 The current nautical charting consists of one 1:500,000 scale general chart, NZ 885 covering the three atolls and surrounding territorial seas. The three atolls of Tokelau are also covered by larger 1:100,000 scale plans. The territorial seas and the route between the atolls has been surveyed to a scale of either 1:50,000 or 1:100,000 but the remaining areas of the EEZ have only been charted from reconnaissance scale survey or general passage soundings. The Tokelau EEZ is charted on small scale ocean navigation charts NZ 14629 (INT 629) scale 1:1,500,000; NZ 14605 (INT 605) scale 1:3,500,000; NZ 14060 (INT 60) scale 1: 10,000,000; NZ 14061 (INT 61) scale 1: 10,000,000; and NZ 14052 (INT 52) scale 1: 10,000,000. 0.3 Hazards to navigation. The majority of the EEZ is very deep-water and there are no offshore features and dangers apart from: a shoal patch reported (1977) some 190 km north east of Fakaofo (in position 7° 43’.3 South, 170° 22.7 West), and reported breakers (1966) west of Atafu towards the outer limits of the EEZ (in position 8° 46’.9 South, 176° 25’.8 West). Considering the amount of fishing vessel traffic near these reported features, and the general depths of 5,000m, neither of these are considered likely to exist or present dangers to surface navigation. 0.4 There is substantial maritime traffic that traverses the Tokelau EEZ, these vessels include tankers, general cargo, fishing, passenger, and occasional recreational and military vessels, however most of this traffic traverses in deep water, generally keeps well clear of the Tokelau atolls and does not pass within Tokelau territorial seas. Occasionally a recreational vessel visits a Tokelau atoll and the current charting is adequate to meet this requirement, especially given the shallow draught of such vessels. 0.5 The only regular ships visiting Tokelau are: a Tokelauan Government general cargo and passenger re-supply vessel on a two-weekly cycle, and a chartered resupply vessel from Apia, operated by the Samoan Shipping Corporation. These vessels utilise local knowledge to augment the charted information and are able to navigate safely with the existing chart coverage. 0.6 As no in-country visit was undertaken during this assessment, there was no opportunity to assess the need for charting of the internal atoll lagoons to support domestic purposes. However, as there are no navigable passages for international vessels into these lagoons there is no international obligation to provide nautical charts of them.
