Jullienne's on screen lesbian relationship with Jay Copeland (Jaime Passier-Armstrong) has been controversial, although the overall response has been positive. On 26 April 2005, the Civil Union Act came into effect in New Zealand, which allowed both heterosexual and homosexual couples to register their relationships officially as an alternative to traditional marriage. On 14 February 2006, the first Civil Union on New Zealand television took place between Maia and Jay.
