A father of two toddlers, aged 3 and 18 months, Slingsby has an extra incentive to stick with the club too.
"I'm on 180 premier games at the moment ... it would be good to reach 200," he said.
With their win against Tamatea, Central are equal on points with Tamatea at the bottom of the points table.
"Like Tamatea, we don't want to be in the situation of playing the promotion-relegation game at the end of the season. We're going up to Taradale with the aim of getting some more points this weekend," Slingsby said.
An interesting aspect of the game will be the likely matchup between the McIntyre brothers out wide; Daniel, who has scored nine tries for Central, and Tommy, who has scored four for Taradale this season.
A keen hunter and fisherman when time allows, Slingsby, also runs his own business Slingsby Spreaders.
January to May is his busiest time of the year and he struggled to make Central's pre-season games as well as trainings during the Nash Cup round.
"That made it tough for me to command a starting spot but work pays the bills."
Slingsby regards former Magpies captains Michael Johnson and Mutu Ngarimu as the toughest loosies he has marked in the competition.
Performances similar to what this pair used to produce at club level from Slingsby and his teammates will be a must during the next fortnight if they are to avoid the dreaded promotion-relegation game.
