Cepheids are key to establishing the cosmic distance scale. Therefore it'simportant to assess the viability of QZ Nor, V340 Nor, and GU Nor ascalibrators for Leavitt's law via their purported membership in the opencluster NGC 6067. The following suite of evidence confirms that QZ Nor and V340Nor are members of NGC 6067, whereas GU Nor likely lies in the foreground: (i)existing radial velocities for QZ Nor and V340 Nor agree with that establishedfor the cluster (-39.4+-1.2 km/s) to within 1 km/s, whereas GU Nor exhibits amarkedly smaller value; (ii) a steep velocity-distance gradient characterizesthe sight-line toward NGC 6067, thus implying that objects sharing commonvelocities are nearly equidistant; (iii) a radial profile constructed for NGC6067 indicates that QZ Nor is within the cluster bounds, despite being 20' fromthe cluster center; (iv) new BVJH photometry for NGC 6067 confirms the clusterlies d=1.75+-0.10 kpc distant, a result that matches Wesenheit distancescomputed for QZ Nor/V340 Nor using the Benedict et al. (2007, HST parallaxes)calibration. QZ Nor is a cluster Cepheid that should be employed as acalibrator for the cosmic distance scale.
