We are looking for plenty of helping hands for a community planting day at Wattle Farm Reserve in Manurewa on 1 September.   

Hundreds of plants need to be planted along the banks of the stormwater sediment fill area at the park, part of a $3.5 million improvement project at the site.

“Overall we will be putting in about 6000 plants over the next few months,” says project manager Auckland Council Healthy Waters specialist, Pradip Baisyet.

"This planting day is a chance for the community to get involved in a project they’ve seen going on in their backyard for several years."

The event is being led by the Wattle Downs Residents’ Association.

Association vice president Sue Matete was recently joined by Manurewa-Papakura Ward Councillor Daniel Newman and Manurewa Local Board Chair Angela Dalton to get the planting underway.

“This is a really impressive project that has been a huge investment by Auckland Council and will have major benefits for locals and the environment from improved water quality to managing sediment and reducing adverse impacts on the Manukau Harbour,” says Cr Newman.

Manurewa Local Board Chair Angela Dalton says as well as the environmental benefits of the project, the area is also a hit with recreational users, such as model boat racers.

“What’s really nice is that while this is a major infrastructure project, it has been done in a way that means it’s still very attractive to look at and a place the community can enjoy.”
