The win moves Auckland above Canterbury into second in the Premiership, five points behind Tasman who play North Harbour tomorrow afternoon. Counties remain last, three points behind Harbour.
Also last, in the Championship, are Southland, who saw their best chance to snap their three-year losing streak vanish in the second half against Manawatu.
Leading 26-7 at the break, Southland imploded to sink to a 31-26 defeat — their 27th consecutive loss.
Having scored four first-half tries, it looked as if Southland would finally claim a win, but two quick tries after the break through unwanted All Black Ngani Laumape put Manawatu right back within striking distance.
A further try to Rhys Pedersen and conversion from Otere Black put Manawatu in front, and Black added a penalty before Manawatu hung on for a remarkably unconvincing victory.
Southland pick up two bonus points for their efforts — their first points of the season — but remain anchored to the bottom of the Championship ladder. Manawatu sit in fifth.
Bay of Plenty are second in the Championship after beating fourth-placed Taranaki 31-17.
