Toroa's two wheelhouses rebuilt by Colin Brown Shipwright and returned to the Selwood Road site. About 300 hours work by Colin Brown, Colin Davidson and apprentice Josh Hawke went into the restoration, using traditional methods.
The wheelhouses' solid sills or deck-logs of 150mm x 100mm kauri -- cut to the curve from straight timber -- were replaced by sweeps that were already curved because they came from a giant Coromandel kauri tree stump. No glue was used – the timber members were locked together with dowelled mortise-&-tenon joints. as the builder George Niccol had done in the original construction.
The restoration of the wheelhouses was funded by a grant from the Waitakere Licensing Trust.
Work begins to establish a method of bending frames for the central engine-&-boiler space of the hull. Attempts to cold-bend the steel frames using a press were undertaken by Marine Steel and by VT Fitzroy at the Devonport Naval Dockyard, however the bulb angle insisted on bending just as much sideways as in the proper plane. A section rolling machine developed by Andrew Macbeth suffered the same problem, but later proved perfect for bending steel-angle deck beams. The Dockyard subsequently lent the Society a number of cast-iron dog-slabs and ADM Contractors Ltd. set up to hot-bend the frames in the traditional way but using a large oxy-acetylene torch instead of a furnace to provide the heat.
Further difficulties were overcome in making the tight bend in each frame each side of the keel and the first complete frame was bolted into the hull at the end of 2008.
