But ruck penalties conceded let Manawatu's Otere Black kick two quick penalties to regain the lead. From the restart, the Steamers put together their best concerted attack of the season, which captain Retallick finished off with a try in the corner.
The Steamers had the lead 12-9 after 30 minutes play but in the final 10 minutes before the break, Manawatu scored two tries as the Steamers fell off tackles. Fullback Nehe Milner-Skudder was a key factor as Manawatu went to halftime leading 21-12.
The game looked all over before prop Mike Kainga and Joe Royal scored late tries to set up an exciting finish.
