Matthams Lane in the suburb of Cashmere, Christchurch

Matthams Lane in Cashmere and this lane doesn’t seem to actually exist. There are 6 houses here but the addresses for them are 44 Bowenvale Ave. They are B, C, D, E, F and G. There is a sign post for this lane and it is on google maps. There is even street view for the lane. There is a map on the council agenda for 2004 showing the lane but it isn’t on any other official websites. Real Estate agents have the Bowenvale Ave address with Matthams Lane in brackets. I am assuming that it is named after a person because of the s at the end of the name.
