In 2013, two new shell doors on deck 3, and two new accommodation ladders on deck 5 were designed and installed by Taranaki engineering firms ITL and EHL. Marine Industrial Design and Babcock NZ made the necessary structural changes. The RHIB was able to be relocated as a result of the innovative design of the new accommodation ladders which can stow compactly inside the ship (5m × 2.5 × 2.5m), rather than being externally stored alongside the ship as before. Improved design of the ladders and the relocation of the RHIB has increased the safety and capability of the ship is no longer compromised.
