Round five Auckland premier rugby action kicks off tomorrow with some fierce rivalries ready to fire. In the blue pool, the battle of the east gets under way at Bell Park as Pakuranga host defending champions University. Pakuranga lifted the Sir Fred Allen Challenge Cup beating Waitemata 22-7 in round four, while University ran riot over Maungarua in their 89-5 victory. Maungarua will find life a bit easier against Waitakere City at Fergusson Park where both sides will be hunting for their first win of the season. Suburbs host archrivals Waitemata at Shadbolt Park and Otahuhu head to Papatoetoe. Over in the white pool Ponsonby and Grammar TEC, both fresh from wins, face off at Orakei Domain; East Tamaki host Eden; Marist are at home against Manukau; College Rifles have the bye.
