New Zealand Cricket and DB Breweries will be reviewing the terms and conditions of the Tui Catch A Million campaign before the next Black Caps fixture.
It comes after safety concerns were raised about the competition during the Black Caps' win over the West Indies in Mount Maunganui on Wednesday night.
Those wearing the Tui orange T-shirt can win $50,000 for catching a six with one hand. There were 24 sixes during the game.
At one point, a man launched himself towards an approaching ball only to fall on a woman sitting in front of him.
Another attempt saw a competition hopeful rush forward for a catch and tumble over a young boy on the bank.
