“We believe we promote responsible gambling and we have no intention of targeting children through our advertising. At all times we comply with all relevant codes,” he said in a statement.
“In the first two rounds we presented at some times alongside Nine commentators but not as a commentator rather as a broadcast sponsor.”
He said there was now no interaction between himself and commentators.
“This type of arrangement by our company, and others, in this and other industries is vital in keeping TV a viable and relevant medium to promote business,” he said.

Waterhouse said his deal with Nine was commercial-in-confidence.
