Scott Robertson's men scored 28 unanswered points in the final 33 minutes to deny the Blues their first win in the city since 2004, the match memorable for the length-of-the-field try started and finished by the one and only Carlos Spencer.
And there was a hint of Spencer's skills in the way Pulu, the former Chiefs and New Zealand sevens player, passed the ball out of the back of his hand, followed up, and crashed over for his try.
It was the continuation of his outstanding form for the Blues since joining in the off season and he must be back in the frame for the All Blacks.
He has played two tests - at the end of 2014 - but has had to fight back from two broken arms over the past couple of years and now that Chiefs rival Tawera Kerr-Barlow has announced he will be leaving for French club La Rochelle at the end of the year, Pulu should get a chance to impress on the All Blacks' November tour at least.
Aaron Smith and TJ Perenara were the two halfbacks favoured by the All Blacks selectors last year, and Smith's struggles on and off the field in the latter part of last year have provided more opportunities for Perenara.
It is one of the most tightly contested positions in New Zealand rugby at the moment, with Pulu getting the better of Smith at Eden Park recently, and Kerr-Barlow dominating Perenara in the Chiefs recent victory against the Hurricanes at Waikato Stadium.
The battle between Perenara and Smith at Westpac Stadium during the Hurricanes' 41-15 win at the weekend was probably a draw, although Perenara was sinbinned for a high tackle and Smith was slightly busier with his running game.
The performance of Pulu will again be crucial for the Blues against the Bulls at North Harbour Stadium on Saturday. The Bulls, with only one win from three matches this season, will look to exploit the weaknesses up front exposed by the Crusaders during their romp home and Pulu's attacking game will be key.
Their littlest player could again prove their most important.
