KEY POINTS:
The bulk carrier Taharoa Express is listing in heavy seas after its load of iron sand shifted overnight.
Maritime New Zealand (MNZ) said it is closely tracking the progress of the vessel but it is making steady progress towards Tasman Bay to seek shelter.
The 140,000 tonne bulk carrier was at the centre of a maritime incident in 2004 when it lost power and drifted towards a beach on the west coast south of Auckland.
MNZ said that at 2.30am today the vessel reported that it had a problem after its load of iron sand shifted while in rough sea about 78km south west of Cape Egmont. Its normal run is from New Zealand to China.
The vessel is intact and not taking on any water, and all 25 crew are safe.
While MNZ is concerned and is keeping a close eye on the situation, there are no reports of the vessel being in danger or distress.
The Port of Taharoa pilot and loading master is on board the carrier and is overseeing its progress as it heads for the more sheltered waters of Golden Bay.
MNZ is in direct communication with the vessel and is receiving regular progress reports.
It was estimated it would reach the Golden Bay area about 1pm.
Plans are in place to respond if the situation changes. Winds are currently around 45-50 knots.
