Whangarei Girls' High School's great expectations fell flat after the mysterious disappearance of three billboards.
Amid dozens of council and mayoral candidates' billboards, Girls' High students put up the signs to promote the school production of Great Expectations by Charles Dickens.
Two days after signs were put up by students on Riverside Drive and Maunu Rd they were snatched from their spot on prepaid council sites last week.
William Walker, teacher and director of the production, said he was perplexed by the development.
A third sign on Hatea Drive had been taken down on Sunday.
