The Blues are right in playoff reckoning in the Super Rugby competition after the Auckland-based side beat the Highlanders 30-12 on Saturday night at Eden Park.
That moves the Blues up to the last playoffs place in sixth, and they now trail double defending champions the Chiefs by just a point in the local conference.
Blues coach Sir John Kirwan's praising his forwards and the defence for their three-try effort and keeping the Highlanders tryless, all 12 points coming from the boot of visiting first five Lima Sopoaga.
George Moala, Ma'a Nonu and Charles Piutau scored as a direct result of the Highlanders' failure to clear their own territory, while first five Simon Hickey added 15 points from the boot for the Blues.
Highlanders player Kane Hames has been cited for alleged foul play for a dangerous charge at the Blues' Hayden Triggs in the 59th minute.
The Sharks continue to lead overall after beating the New South Wales Waratahs 32-10. Elsewhere the Queensland Reds edged visiting South Africans the Stormers 22-17.
