They have a bye next weekend, but their last two opponents, the Highlanders and Crusaders, will already be scenting blood.
It was late in the first half when they finally succumbed to the pressure applied by the black-and-yellow wave, with prop Chris Eves going over from close range and halfback TJ Perenara following suit from the back of a ruck. The free-flowing moves were confined to the first minute when Victor Vito went close but his flicked pass went astray and the Blues went on a breakout thanks to his impressive counterpart Akira Ioane.
Their first-half performance effectively shut the Blues out and Kirwan's men made too many handling mistakes to put the Hurricanes under sustained stress. Poor Lolagi Visinia attracted Julian Savea like iron filings to a magnet and, apart from Matt Vaega's try, there was no way through.
It all adds up to good news for Chris Boyd's team as the New Zealand weather closes in and they head towards the business end of the competition, a time when improved defences and the need for risk-free rugby combine to make matches more armwrestle than exhibition.
The Hurricanes had grafters in Jeremy Thrush, Mark Abbott and Blade Thomson, with Dan Coles, another try scorer, Victor Vito and Ardie Savea capable of supplying the x-factor.
It was an statement-type performance from the visitors' pack in the swirling drizzle which had followed heavy rain. It was exactly what was required and that's why the many Hurricanes fans huddled against the cold and wet were smiling so much as they left.
Top of the table and with no apparent weaknesses, they can expect a few more highlights yet.
