The $3 million third stage of improvements to the Awanui flood scheme is progressing well, according to the Northland Regional Council.
Councillor Colin Kitchen, the regional council's Te Hiku representative, said the third annual construction season of the $15m scheme upgrade was now expected to be completed in 2022/2023.
About $1.1m worth of work had been done last construction season, but a subsequent multimillion-dollar injection from the Government as part of its Covid-19 recovery response package was allowing the project to be completed more quickly and at less direct cost to ratepayers.
This construction season's schedule was costing about $3,050,000, including extensive earthworks for southern spillways under way over about 2.4ha of former farmland behind Rongopai Place, in Kaitaia, including construction of 280m of new stopbanks to better protect 29 flood-prone homes in Rongopai Place, and about 900m of new spillway.
Kitchen said the $1.1m spillway work would account for more than a third of this season's programme, and was now 90 per cent complete, although the spillways would not be used for the next year or two, to allow grass to become well-established.
