Photo \/ Mark Mitchell<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">The 2025 retirement meant KiwiRail could avoid paying $12 million to dry dock the ship in Singapore, which resulted in a forecast $7m net financial benefit to KiwiRail over two years, as opposed to a 2026 retirement.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">Following the release, the Herald asked how much KiwiRail had paid for the consultants\u2019 report. KiwiRail refused to disclose the figure, again citing commercial sensitivity. The Herald has again appealed to the Ombudsman.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">A commercial in-confidence briefing to Peters said it was \u201csimply not commercially viable to continue to operate Aratere for the relatively short window between its return from drydock and its Picton wharf needing to be demolished\u201d.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">However the KiwiRail briefing warned retiring Aratere \u201cwill create a four-year gap in rail-enabled ferry operations to 2029\u2033.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">\u201cThe withdrawal of Aratere will reduce the capacity of the Interislander fleet from three ships to two and the overall market capacity to transport freight across the Cook Strait.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">\u201cKiwiRail will prioritise rail freight and commercial vehicle customers. Private vehicle and foot passengers will face capacity pressures particularly during the summer peak.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">\u201cThe withdrawal of Aratere will put greater pressure on Interislander to maintain its high level of reliability, this will be mitigated through the rigorous application of proactive maintenance.\u201d<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">After the Ombudsman ordered the documents be released, KiwiRail provided copies that were still heavily redacted. The Herald challenged the extent of those redactions with the Ombudsman, who advised that much of the redacted material had in fact been cleared for release and should not have been redacted.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">KiwiRail blamed a \u201cmix-up\u201d and said it had accidentally supplied an earlier, more heavily redacted version of the documents. <\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">It later released revised copies with significantly fewer redactions, but much of the rail freight financial impacts of retiring the ship remained withheld.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">The state-owned enterprise said it accepts the Ombudsman\u2019s findings, and now believes the risks of the information\u2019s commercial sensitivity is reduced.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">A spokesman for KiwiRail said the removal of the ferry has meant \u201cless flexibility at peak times\u201d.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">\u201cServices have continued to operate safely and reliably, over the last 12 months our reliability to sail, excluding weather is over 99%.\u201d<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">\u201cKiwiRail engaged extensively with freight customers, industry partners and the wider supply chain to plan for the transition to a two ship fleet,\u201d the spokesman said.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\">The Aratere, since renamed Vega, has now left New Zealand and is en route to India <a href=\"https:\/\/www.nzherald.co.nz\/nz\/wellington\/interislander-aratere-ferry-sold-for-scrap\/7OQWEOIF2VAXHF3A2UX735KYC4\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.nzherald.co.nz\/nz\/wellington\/interislander-aratere-ferry-sold-for-scrap\/7OQWEOIF2VAXHF3A2UX735KYC4\/\">to be scrapped<\/a>.<\/p>\n<p class=\"EoZyGajGNiPxVf\" style=\"display:none\"><a href=\"https:\/\/www.nzherald.co.nz\/author\/ethan-manera\/\" target=\"_self\" rel=\"nofollow noopener\" title=\"https:\/\/www.nzherald.co.nz\/author\/ethan-manera\/\">Ethan Manera<\/a> is a Wellington-based journalist covering Wellington issues, local politics and business in the capital.
