Mr McKenzie said less than 2000 tickets were available for the match, which was almost certain to sell out.
"When Australia is very competitive, the Bledisloe Cup matches are very keenly anticipated," he said. "But this is absolutely shaping up to be a real battle."
TAB bookmaker Mark Stafford said with the Springboks in good form and All Black captain Richie McCaw out injured, New Zealanders were putting their money on the Springboks - who were yesterday at long odds of $3.30. The All Blacks are paying $1.30 for the win.
"[The Boks] are in good nick and they haven't lost for a long time. People have seen the odds and are saying 'that can't be right' and they're putting money on it," he said.
Money bet on a Springbok win was yesterday six times more than what had been placed on the All Blacks, Mr Stafford said. The biggest punt so far was a $4000 bet at $3.80 for a South African win - which, if successful, would pay about $15,000.
"For the winning team and margin most of the money is again on South Africa for the win at 12 and under, then New Zealand at 12 and under and then South Africa 13 and over.
"Virtually no one has put money on New Zealand to win at 13 and over."
South Africa, who last won at Eden Park in 1937, have named an unchanged 23-man game-day squad for the test with the same team that trounced the Wallabies 38-12 in Brisbane last Saturday.
Worst weather to pass by test
Rugby-goers can rest assured, the storm battering the country is forecast to be clear of Eden Park by kickoff on Saturday night.
MetService meteorologist John Law said there was a chance of showers and a southwesterly breeze, but overall it would not be a bad night to be sitting in the stands.
"The worst of the rain should clear away as we head into the weekend so for Saturday it's not really looking too bad. There are still a few showers around and there will be a southwesterly breeze for the game itself but it's just about dry at Eden Park.
"The next couple of days we have some really fairly windy and wet weather for Auckland, the front is moving its way up the country ... but as the whole system pulls away you'll find an improving story for Friday which should be a pretty decent day."
Temperatures were due to drop slightly so fans should rug up, he said.
