Nerwress tore his calf muscle in the warm-up and there were fears he could be gone for the season.
But Toa has been bolstered by the inclusion of former top player Tu Umaga-Marshall, 36. He has played the last couple of games at 1st five-eight, although his preferred position was 2nd five-eighth.
Umaga-Marshall has played for Wellington, Canterbury, Crusaders and Hawkes Bay in the past.
Meanwhile, a log jam was starting to develop in the middle of the points table, with Paraparaumu sitting just outside the top four with Rahui on 17 points apiece.
Rahui and College Old Boys still have a game in hand though, having already sat out their quota of byes.
Shannon continued their good run of form by beating Rahui 26-8 at Shannon Domain. Both sides are still in with a shot at the chocolate.
The season was all but over for College Old Boys who were in last place with just one point for the season.
Everyone gets a rest as there is no club rugby over Queen's Birthday weekend, however there is a trial match for the Heartland team at Levin Domain tomorrow night,
