We are the registered producer statement authors who can issue the producer statements on the membrane installation.
Auckland Council says " We may accept a producer statement from a council-approved expert as evidence that their design or building work complies, or will comply, with the Building Code.
We must only issue a building consent or a code compliance certificate if we are satisfied on reasonable grounds that your building work complies or will comply with the Building Code and a producer statement is one way of helping us decide. "
