Narrative:
ZK-NGK, an Air New Zealand Boeing 737, en route from Wellington to Auckland, was landed at Royal New Zealand Air Force (RNZAF) Base Ohakea as a precaution because of fumes in the cockpit from electrical burning. Nobody was injured in the incident.

The electrical burning resulted from a coffee spill in the cockpit by a different crew about 4 hours earlier. As the coffee dried, the sugar content provided sufficient conductivity to bring about a slow electrical breakdown, which resulted in spurious warning light indications, electrical burning of an avionics component and an eventual short circuit.

Management of crew drinks in the cockpit was a known hazard that had been identified, documented and mitigated by standard operating procedures. A safety issue identified was the need for flight crew to make maximum possible use of available resources, including those beyond the cockpit, during emergency and non-normal situations.
