Also unbeaten are Waipu, who ground out a 17-8 victory over Western Sharks.
Waipu are in the same boat as Kamo, whose lack of bonus points has stopped them from leading the pack despite not suffering a loss.
Hot on the top three's heels are Hikurangi and Old Boys Marist, who both picked up wins in the Easter round.
Both sides also collected valuable bonus points. Hikurangi managed a 29-5 win over Hora Hora while OBM ground out a 22-10 win over Wellsford.
After a scrappy first 40 minutes between OBM and Wellsford it was still anyone's game.
However, an early try in the second half to the visitors showed who was fitter and more determined to win the back and forth battle.
Hikurangi and OBM are battling out for the fourth spot on the ladder, which Hikurangi currently has.
