Dunedin tourist attraction Cadbury World will remain open despite the planned closure of Cadbury's manufacturing plant in the city.

Cadbury owner Mondelēz International today announced its plan to move manufacturing to Australia, with the loss of 350 jobs in Dunedin.

In a statement the company said it remained committed to Cadbury World, which attracts 110,000 visitors a year.

It did not specify how the attraction, which features a chocolate waterfall and tours of the chocolate making process, would be affected by the closure.

"The company is ready to invest in redevelopment work to make Cadbury World an even better visitor experience," Amanda Banfield, Area Vice-President for Australia, New Zealand and Japan, said in a statement.

The company signalled in January a future expansion of Cadbury World.

A final decision on the proposed redevelopment of Cadbury World would be made by April.
