Currently on Kayak, you can get flights on Air New Zealand from Toronto to Auckland, stopping in Vancouver there, and L.A. back, from $730! Whether these tickets will be honoured, time will tell. When I try on Google Matrix, these prices are NOT showing up so that's a bad sign.
Available dates seem to be in mid-June, returning either after a couple of months or even as short as 3 1/2 weeks.
This link will take you to the Kayak deal for the dates June 19th to July 14th for $730.
