The natural habitat - and concerns about youth - are on the agenda in Waitakere.

Clean and green is a key message in the Waitakere ward, as the environment continues to feature highly among residents' concerns.

The ward is made up of two local boards - Henderson-Massey and Waitakere Ranges - so has two seats to fill.

Dr Mels Barton, chair of the Titirangi Residents and Ratepayers Association and secretary of the Tree Council, said people were "frustrated" with being shut out of decisions regarding the environment.
