Seton Nossiter Park is a 30-hectare bush-clad reserve in Belmont Gully on Wellington’s northern edge, spanning the suburbs of Grenada Village, Newlands and Paparangi.
The park protects a stream corridor with regenerating native forest and remnant stands of titoki and tawa. It offers walking tracks, an off-lead dog exercise area and permitted mountain biking through a sheltered gully setting. The reserve also preserves historic concrete abutments from an 1885 timber viaduct that was once New Zealand’s largest.

About Seton Nossiter Park
Seton Nossiter Park lies in Belmont Gully between Grenada Village and surrounding northern suburbs. Belmont Stream runs through the reserve, supporting a mix of regenerating bush and remnant original forest including stands of titoki and tawa. The park is named after Seton Nossiter, a local farmer and councillor who served on the Hutt County Council and later Wellington City Council.
The reserve protects a significant gully corridor that provides habitat and connectivity for native wildlife amid suburban development. A community working group supports ongoing revegetation and enhancement of native vegetation in the park.
Historic features include the concrete abutments of a timber viaduct built in 1885 by the Wellington and Manawatu Railway Company. Two of these abutments remain visible in regenerating bush near the Mark Avenue entrance.
Walking and Activities
The main track begins with an easy walk from the Mark Avenue car park along the valley floor, crossing the stream via stepping stones in places.
Further up the valley the track passes the dog exercise area and an open picnic spot beside the stream before climbing steeply in sections to the Colchester Crescent entrance in Newlands. The full length of the main track is approximately 1.6 km.
Mountain biking is permitted on the tracks. The off-lead dog exercise area extends from roughly halfway up the valley to the stand of titoki and tawa.
