I'm contacting you on behalf of Heritage New Zealand (HNZ) who own Ruatuna Farm and homestead, 441 Tinopai Road.
Over the past 10 or so years some "seedling" macrocarpas have grown to medium sized trees hanging over the fire sprinkler system shed and interfering with the outlet to the septic tank, and will require some careful felling and chipping. The attached pic shown their approximate location. There is a staff member on site Thursdays who can provide a closer ID of the offending trees.
Would be grateful if you would contact me in the first instance to arrange access and identification of the trees to be removed.
