The clean-up starts at 9am and runs for an hour before the planting starts. She said the area doesn't look too had but you can always be surprised.

MP Shane Reti: Dumping of hazardous waste into Northland stream unacceptable
"In the past the community has pulled an entire car out of the stream."
Lee expects the clean-up will mainly find windblown rubbish and items thrown out of cars such as bottles and fast food wrappers.
She said the planting of more than 650 trees is part of the Matariki Tu Rākau commemorative community tree planting programme.
"We wanted to do something a little more lasting."
She hoped it would give the area some importance and the community would help maintain it.
The Matariki Tu Rākau programme encourages communities to plant trees in recognition of the service of the men and women of the New Zealand Defence Force. Lee said the Whangārei RSA was supporting the event, and would be attending on the day.
The plants include kahikatea, manuka and cabbage trees, flaxes and grasses. The event will also have a free barbecue, music and giveaways.
F.O.R.C.E is run by Lee and partner Nicholas Connop, aka the Whangārei Rubbish Wrangler. The pair have been organising monthly clean-ups for more than eight months.
This year the group have removed about three tonnes of rubbish from the Whangārei environment. Numbers of volunteers have steadily grown at the clean-ups, reaching 50 at the last one at Waiarohia Park.
Anyone is welcome to join them next Saturday - for more information check their Facebook page.
