From next year it will run 24 hours a day displaying stock prices, currency and latest news headlines.
Bennett said the NZX had displayed stock exchange information in the past in its Auckland office and the AMP Building on Albert St also had a stock price board.
But this would be the first time a display had been put up in a public place.
"What we have learned from around the world is the need to have a public presence."
The ticker board is the largest high definition screen in Australasia.
The NZX has recently moved into offices on the seventh floor of the Zurich building and is expected to boost its Auckland staff to 20 next year. A year ago they had just one person based in Auckland. The company has 183 staff in total.
Bennett said he expected 2014 to be a "terrific year" for the stock exchange. The NZX50 Index is up 17.9 per cent since the start of the year following a 24 per cent increase in 2012.
"We see the global economy recovering quite well. There is less uncertainty globally. The New Zealand economy could have one of the best years in generations."
Bennett said with business confidence hitting an all time high and companies looking to grow the stock market was one option companies could look to for raising capital.
"We see a reasonably good listing pipeline."
The NZX will also launch a new growth market in the second quarter of 2014 and equity derivatives for institutional investors.
"All of those things point to a great year next year."
