Aratere: Minimal damage... - Financial Unions

Ferry operator Interislander says the Aratere will be brought back into port on Sunday while an investigation into the stranding continues.

The Interislander vessel lost its steering and ran aground near the port on Friday, before being successfully refloated on Saturday night.

Interislander executive general manager Duncan Roy said on Sunday morning divers had checked the hull and found it was still water-tight, and there appeared to be minimal damage to the vessel.

But an in-depth look at the state of the 26-year-old vessel was yet to be undertaken.

"The report from the people on the ship is they've tested the tanks, the divers have tested the hull and its operation."

Another Interislander ferry, the 26-year-old Kaiarahi, would be back in service on 3 July. Only one ferry, Kaitaki, was operating in the meantime. Roy said Kaitaki had been operating with "100 percent reliability" of late.

Just days before the Aratere's accident, Transport Minister Simeon Brown raised concerns about KiwiRail's maintenance of its fleet at a meeting of the transport and infrastructure committee.

"We also want KiwiRail to make sure they're maintaining their existing boats to the appropriate standards, which has been a significant issue that we've been highly unimpressed with coming into government."

KiwiRail chief executive Peter Reidy did not want to comment directly on the minister's claims, but defended the Interislander's recent record.

"I'm incredibly proud - the last 18 months there's been a very big investment programme. You can see the ships in the dry docks, a big lift in capability. The last nine months we've had 99.6 percent reliability, on-time performance 92 percent - that is higher than global airlines. So we are very disappointed about what's happened in the last 24 hours.

"We'll do the work, we'll do the investigation, but we're very proud about what Duncan and the team have done to lift the performance of these ships… I'd take my own family on those ships right now."

Reidy said he had a "very frank" conversation with the transport minister on Saturday night, during which the minister praised the successful refloating of the Aratere.

Roy said the Aratere had just been upgraded with a new steering system, seven kilometres of cabling, and a "new automated approach".

"The original steering system was coming into obsolescence and there wasn't enough repair parts in the industry that we were happy with. So we made the decision to preemptively replace that with a new, state-of-the-art system which we brought in with international partners."

He said the "comprehensive investigation" into the cause of the accident would include examining that new steering system to see if it was at fault.

Asked if they had a potential timeframe for the Aratere to be back in service, Roy said "no", saying they would wait for the investigation and they they would "have the facts".

Late last year, the government canned the Inter-Island Resilient Connection (iReX) project - which included two brand-new ferries - due to its budget blowing out from $1.45 billion in 2021 to $2.6 billion in 2023.

The New Zealand Council of Trade Unions on Sunday said it was "beyond time" the fleet, each nearing three decades old, was replaced.

"Fifteen billion dollars of cargo is carried annually by the Intersialnder - it's in everyone's interest to make sure that the service is seaworthy," said president Richard Wagstaff.

"The decision to cancel the replacement ferries should be urgently reviewed in light of the developments overnight. The replacement ships from Korea could have been here from next year. "

He linked the accident to the recent falling of a pylon, which cut power off to Northland earlier this week.

"Yet investment by government in infrastructure will fall every year under the new Budget. The priorities of this government are all wrong."
