The troubled Singaporean M2 Shiling ship anchored at Tasman Bay is likely to spend another weekend there before its return to Wellington.
Maritime New Zealand says the Shiling cargo ship will remain anchored at Tasman Bay until "at least" the start of next week.
It's been five days since the Shiling anchored at Tasman Bay and Maritime NZ says the Skandi Emerald, an ocean-going tug, has been supporting it.
Once towage plans have been signed off, weather conditions are safe and there is space at the capital's CentrePort, Maritime NZ says the Skandi Emerald will tow the Shiling to Wellington.
"Maritime NZ needs to sign off the plans before the two vessels can depart Tasman Bay."
In a statement, Maritime NZ incident controller David Billington said "moving this vessel safely is a top priority".
Billington said the towing of Shiling is expected to take about 20 hours, with the distance between Tasman Bay to Wellington being between 100 and 120 nautical miles "depending on the route taken".
"This means conditions for Tasman Bay, the Cook Strait and Wellington need to be taken into account when planning the voyage."
Billington said the timings of the tow and its arrival in Wellington are still being confirmed.
"However, an opportunity has been identified for the tow to be undertaken early next week."
Billington added Maritime NZ is working with the Wellington Harbourmaster and Centreport as they all plan for the long journey to Wellington.
