The City Promenade is one of the Government agency, Otakaro Limited's, anchor projects as part of Christchurch's earthquake recovery.

To celebrate the promenade's completion a scavenger hunt will be held on Sunday, 25 November.

Otakaro chief executive John Bridgman, says Sunday will be the first chance for people to walk the City Promenade from end-to-end.

The official opening will take place near the Pegasus Arms at 10am, where people will be able to get an entry form for the scavenger hunt.

Entry form will also be available from the Margaret Mahy playground.

Mr Bridgman said $10,000 worth of prized were on offer from the neighbouring businesses, including a $5000 Discover Travel voucher.

There will also be 20 musical acts playing throughout the day along the promenade, as well as face painting, eel feeding and food trucks.

The promenade covers 2km going from the Margaret Mahy playground to Antigua Boatshed next to the Christchurch Hospital.

A spokesperson for Otakaro says the whole Avon River Precinct, of which the Promenade is the most significant part, cost $120m.

The spokesperson said that project was now largely completed except for a small path from Madras Street to Fitzgerald Avenue.
