Credit Suisse First Boston has been voted the top broking house in New Zealand by the international publication Euromoney.
It won the award for both the best equity and merger and acquisition house for the year ended May.
In naming Credit Suisse, Euromoney highlighted the broker's role in underwriting Westpac's $650 millioncapital placement to its shareholders.
In total Credit Suisse advised on more than $7.5 billion of merger and acquisition transactions and on more than $3 billion of capital raisings. It recently advised on major deals for Fletcher Challenge, Lion Nathan, Carter Holt Harvey and Tower.
"Credit Suisse is the most active stockbroker in the country, and leads in corporate finance market share," Euromoney said.
"Deutsche Bank is throwing down a stronger challenge, and Macquarie is a consistent threat."
Credit Suisse's New Zealand managing director, Bill Trotter, said: "Of particular relevance was the number of projects where a strong Australasian capability combined with global industry and product knowledge were the criteria for success. Delivery of our Australian capabilities is increasingly important to our New Zealand clients."
