The Labour Party leader Jacinda Ardern has announced a $300-million package to help accelerate the Christchurch rebuild.

The money will be used to establish a Global Settlement with the Christchurch City Council, which will settle the long term ownership, liabilities, and ongoing funding for all major anchor projects.

The settlement will distribute money into developing the red zone, contributing to a new stadium, and dealing with the gaps in the horizontal infrastructure programme.

Speaking to a crowd of hundreds of her supporters at the Riccarton Racecourse, Ms Ardern also promised to repair the relationship with the Canterbury District Health Board, as part of a broader review of the DHB's funding model.
