The approach by sea to Port Taranaki is safe and easily navigable, with an open roadstead and anchorage in 18-22 metres of water. Inside the harbour the approach fairways provide a swinging basin of up to 418 metres, and a maximum port draft of 12.5 metres. Vessels can be berthed in most weathers, but ship drafts in excess of 9.5 metres depend on tide. Tidal range is 1.7 to 3.9 metres.
Harbour and berth soundings are regularly checked by the Port Hydrographer. These soundings are not to be used for navigational purposes.
Night berthing operations are restricted in wind conditions in excess of 20 knots and require the vessel's radar and speed measuring devices to be operational.
With Harbourmaster's approval or using the Dynamic Under Keel Clearance system, draft may be increased up to 12.5 metres. This only applies to the Blyde No 2, Moturoa No 2, Newton King No 1 and Newton King No 2 berths.
|Port Tidal Values||Reduced Level||
|New Plymouth fundamental B.m||20.099|
|Wharf deck levels (nominal)||19.000||5.62|
|Mean sea level||15.348||1.97|
The following procedures are effective when assessing maximum draft for vessels transiting and berthing at Port Taranaki.
The following table details the maximum dimensions allowed at each of the port's berths.
|Berth||CD||Max LOA||Max Beam||Max Draft||UKC at CD|
|Breakwater No 1||7.0m||78m||20.0m||6.5m||0.5m|
|Breakwater No 2||9.5m||150m||25.0m||9.0m||0.5m|
|Moturoa No 1||8.5m||98m||20.0m||7.5m||1.0m|
|Moturoa No 2||13.5m||196m||35.0m||12.5m||1.0m|
|Newton King No 1||13.5m||211m||35.0m||12.5m||1.0m|
|Newton King No 2||13.5m||211m||35.0m||12.5m||1.0m|
|Blyde No 1||11.5m||225m||35.0m||10.5m||1.0m|
|Blyde No 2||13.5m||225m||35.0m||12.5m||1.0m|
|Blyde No 3||7.5m||78m||20.0m||6.5m||1.0m|
Any variation from the above is solely at the Harbourmaster's discretion.
|Up to 9.0m||May transit at any time|
|9.0m – 10.0m||Requires Height of tide equivalent to DRAFT minus 9.0m by completion of manoeuvre|
|10.0m – 12.5m||Transits may only be undertaken under the DUKC system|
Note 1: Severe weather may significantly modify these parameters which define fair-weather conditions only.
Note 2: DUKC transits with vessels in the lower range of drafts in excess of 10.0m may well be undertaken at any time, particularly during neap tides, but otherwise some height of tide may be required to undertake the transit.
Note 3: Final DUKC transit drafts are dependant on real time calculations that can only be undertaken within 24 – 36 hours of the actual transit. METOCEAN modelling indicates that transits should be possible at 12.5m for 95% - 97% of all High Waters.
Prior to arrival, the notification times for a vessel are:
Pilotage is compulsory for all vessels of more than 100m in length or 100GRT. Pilots board about 2.5 nautical miles off port from the 'Westgate', a rigid inflatable pilot launch.
The pilot ladder is required to be rigged on the lee side of the vessel as close as possible to midships, 2 meters above the water, with manropes.
Vessels are normally turned and berthed head to sea, and all moorings are supplied and tended by Port Taranaki. Vessels are required to use up to four shore moorings, depending on length, and normally one ship's head line and one stern line. Vessels are boarded on arrival by two Port Taranaki staff to assist in mooring.
