Sykes was replaced at halfback by Mason's brother James, who ended up earning the player of the day award.
Goodhue and Sykes scored first half tries to give Kamo a 17-3 lead at halftime before James Mason and Kurt Benny scored in the second to make sure of their third win in a row.
Although the Sharks couldn't repeat their heroics of last weekend, they never gave up trying and hit back with a couple of late tries to Tony Stokes and Willie Davies, to give some consolation to their travelling supporters.
Kamo still have the return of some injured players, including Bryce Williams, to look forward to and that should give them further belief that they can feature in the playoffs, despite their poor start to the season.
Elsewhere, the experience and polish of Mid Northern was enough to see them home in a close 35-22 win over competition front runners Marist at Kensington. The loss sees Marist drop to fourth with Mid Northern moving up into third.
Mid Western and Wellsford are now joint leaders after good wins on Saturday.

Hikurangi just got up to beat Hora Hora 13-12 in the final game of round eight to score their third win of the season.
