Under the Local Government Act, the council is required to begin consultation on its long-term plan in March.
Now, the council will undertake a new plan, to be called the Christchurch City Three Year Plan, and will commence consultation next month as planned.
Mr Brownlee said this new planning process would give surety to Christchurch rate payers, the people of Christchurch, the New Zealand tax payer, the financial markets and development partners.
"Under normal circumstances a Long Term Plan outlines a council's rating and spending expectations for the next decade but at this stage in the Christchurch rebuild we need a more appropriate planning mechanism that takes into account more immediate goals," Mr Brownlee said.
"Banks, bond markets and ratings agencies, along with businesses and households take significant guidance from councils' Long Term Plans."
Mr Parker said the key benefits for the city resulting from the agreement is certainty around cost sharing arrangements and decision-making processes relating to the central city key rebuild projects, and cost sharing arrangements relating to all other council costs, including horizontal infrastructure.
"The Minister has confirmed these agreements will be in place by the end of April 2013," Mr Parker said.
"Like any business the city council needs to plan ahead and give its people certainty, this three year plan will do that.
"This accord will ensure the Christchurch City Council adopts a sound prudent plan that is fully costed and establishes a solid financial footing for the city's future."
Cera's powers will be invoked to allow the Long Term Plan process to be deferred until 2015, by which time a cost-sharing method will be worked through between the Crown and the Council.
"City councillors, along with the Crown, are committed to presenting the most realistic and achievable process to shoulder the financial burden caused by this series of catastrophic earthquakes, with a joint aim of rebuilding the city to be the very best it can be," Mr Brownlee said.
