Ranfurly Shield

Manawatu began the season as holders having defeated Auckland in the 1976 season. In 1978, they defended the shield in four matches, extending their tenure to 13 successful defences before being defeated by North Auckland. North Auckland chose not to accept any more challenges in 1978 and thus held the shield for the summer.
