A full stadium of 28,000 fans await the British & Irish Lions and the Maori All Blacks for the eagerly awaited fifth match of the DHL New Zealand Lions Series.
The international rugby action gets under way with the Black Ferns taking on England at 4.15pm in the final match of the Women's International Rugby Series with gates opening at 4pm.
Cass said it was shaping up to be a special time in Rotorua.
"The support from the community in Rotorua and across the Bay of Plenty this week has been immense. The excitement leading up to the Maori All Blacks and British & Irish Lions match, as well as the Black Ferns and England game is fantastic," Mr Cass said.
"Having the region bustling with locals and visiting fans and the stadium packed to capacity for the game will make for a very memorable and unique time."
New Zealand Rugby said the additional activity in Rotorua prior to the match, including a world record attempt to stage the largest ever haka, would profile Rotorua around the world.
"With more than 100 international media in town and a global reach of more than 200 million for the match, it's set to be a great showcase for the city."
Fans are encouraged to head out towards the stadium as early as possible after the Giant Haka as the Australian and Canadian International Women's Rugby teams face off at Smallbone Park at 12.30pm.
