From time to time it is necessary to renew the lashings on a waka which secure the rauawa (topstrakes) to the hull.  Lashing is typically done working in pairs.  The technique involves a series of locking knots as the lashing is passed through the hull.  Pegs are use to hold the lashing in position while tension is applied.  A caulking is applied between the rauawa and the hull to seal the joint.  The same technique is used for the tauihi and taurapa.  Joins in the rauawa are typically towards the ends of the waka.
