The Crusaders are reportedly close to signing All Black wing Julian Savea from the Hurricanes.
And the seven-time champions have signed Counties Manukau midfield back Rey Lee-Lo for the next two Super Rugby seasons.
Lee-Lo played his debut Super Rugby season with the Hurricanes last year after being part of the Chiefs development squad in 2011.
The 27-year-old will continue to play his provincial rugby with Counties.
