Namibia Wildlife Resorts Managing Director, Matthias Ngwangwama says that about N$ 100 million is needed to upgrade the dilapidated Zambezi Waterfront Tourism Park, which closed its doors in 2016 following allegations of maladministration, in order to bring it on par with other international tourism parks.Stressing that the Zambezi waterfront is located in a strategic area and is a gateway to Southern African Development Community countries such as Botswana, Zambia and Zimbabwe, Ngwangwama called on local and international investors to form a public-private partnership to invest in the facelift of the facility.
