Dildo singers protest at NZ Prime Minister

The trend of inserting phallic objects into New Zealand politics continues as protesters dressed as sex toys crashed an event attended by Prime Minister John Key.

Four singers dressed in pink jumpsuits stood on a boat and performed a satirical protest song referencing the government's regional economic policies including the controversial TPPA.

The adults-only protest comes just five weeks after New Zealand Minister for Economic Development Steven Joyce was hit in the face by a dildo thrown by an activist.

The video of the Joyce incident went viral and was parodied by comedian and US talk show host John Oliver.
