$\hat{ Z}$-invariants, which can reconstruct the analytic continuation of the SU(2) Chern-Simons partition functions via Borel resummation, were discovered by GPV and have been conjectured to be a new homological invariant of 3-manifolds which can shed light onto the superconformal and topologically twisted index of 3d $\mathcal{ N}=2$ theories proposed by GPPV. In particular, the resurgent analysis of $\hat{ Z}$ has been fruitful in discovering analytic properties of the WRT invariants. The resurgent analysis of these $\hat{ Z}$-invariants has been performed for the cases of $\Sigma(2,3,5),\ \Sigma(2,3,7)$ by GMP, $\Sigma(2,5,7)$ by Chun, and, more recently, some additional Seifert manifolds by Chung and Kucharski, independently. In this paper, we extend and generalize the resurgent analysis of $\hat{ Z}$ on a family of Brieskorn homology spheres $\Sigma(2,3,6n+5)$ where $n\in\mathbb{ Z}_+$ and $6n+5$ is a prime. By deriving $\hat{ Z}$ for $\Sigma(2,3,6n+5)$ according to GPPV and Hikami, we provide a formula where one can quickly compute the non-perturbative contributions to the full analytic continuation of SU(2) Chern-Simons partition function.
