Leave the Poteriteri - Teal Bay track at its high-point just north of pt459 and climb south to pt459. A good pen ridgeline with good deer trails leads generally south over pt499 (turn sharply east from the summit), pt398, pt398, pt367, pt211 and pt210. From 211 south progress becomes ferny and slow. Follow the main ridgeline slightly east of south off pt210 towards the Crombie flats below.
An east-west tracking tunnel line is intercepted around the 160m contour (40m above the flats below) and is marked with yellow triangles and an assortment of tape.
