UWISH2 is the first unbiassed imaging survey of v =1 − 0 S(1) molecular hydrogen emission (λ = 2.122~μm) in the northern Galactic Plane. Here we discuss 284 extended emission line objects which we consider to be candidate planetary or pre-planetary nebulae. Some are clearly associated with known PN, but the majority (60%) have no previous detection. We have classified the objects according to morphology and find 53% are bipolar with half of these being new detections. The remaining objects are mostly elliptical/round (35%), fainter than the median sample flux (4.4 × 10−17 W m−2) and previously undetected (74%).
