Far North District Council and Tararua, Central Hawkes Bay, Tasman and Matamata-Piako district councils had also scrapped the annual process.
WDC would still prepare, adopt and make publicly available the 2017-18 Annual Plan and people wanting to discuss the plan could contact WDC or a local councillor, who would be discussing the plan at council meetings.
The upcoming year featured projects such as a new freshwater treatment plant close to Whau Valley Dam, the creation of a new park by the Canopy Bridge, the Laneway extension down James St, continued improvements at the Loop, and the search for the best options for a new council building.
Works would also include the $4.4 million Tarewa Park underground wastewater storage and treatment tank and $2m for Stage One of the Hikurangi wastewater system upgrade.
"We still have an obligation to openly provide detailed information to the community about our programmes, expenditure and income (including rates) and nothing will change about that," said Ms Mai.
Public engagement would begin in mid-2017, with the formal process starting in March 2018. The 2018-28 LTP would be adopted in June, ahead of council's 2018/19 financial year which started in July.
Last year was the first in which WDC did not have to consult under the Local Government Act 2002, but it volunteered to do so, with community engagement events, a consultation document, and collating, summarising, considering and responding to submissions.
In last week's meeting some councillors objected to the change, including Phil Halse, who said the process would leave council subject to "backdoor politics".
Councillor Crichton Christie said the annual process allowed members of the public to "express concerns about issues".
Meanwhile, councillor Trisha Cutforth said she feared it would set a precedent for a slippage of public engagement.
However, those seeking to bring projects, campaigns, concerns, issues and requests to council could still do so, by contacting local councillors.
