Cape Town - Bulls captain Pierre Spies believes the more structured game employed by his side could come in handy when they face the adventurist Blues in their first Super Rugby tour match in Auckland on Sunday.

The Blues, who finished a lowly 12th on the overall log in 2012, are a different side this year under the guidance of former All Black wing John Kirwin and started the season like a house on fire.

They have notched impressive victories over the Hurricanes (34-20) and Crusaders (34-15), scoring nine tries in the process and will be confident to bag a hat-trick of wins when they face the men from Pretoria, who have never won in Auckland.

But Spies, whose men are also unbeaten following wins over the Stormers (25-17) and Force (36-26), believes the Bulls' conservative approach could make life difficult for the New Zealanders.

"It will be a different type of match from the ones they had in the first two weeks," Spies told the Beeld website.

"They have only played against New Zealand teams," Spies said, referring to the Kiwis' more expansive type of approach which plays right into the hands of the Blues.

Spies though, did acknowledge that the Blues are different team with "new vigour, structures and players" under Kirwin.

The clash at Eden Park kicks off at 05:05 (SA time) on Sunday.
