Two Kaitaia Fire Brigade crews were faced with what deputy Chief Fire Officer Ross Beddows described as a shambles when they responded to a crash on the Awanui Straight south of the Quarry Road intersection on Thursday night.
None of those responsible had waited for emergency services to arrive.
The alarm was raised at 9.25pm, and the crews found a four-wheel-drive nose down in the drain, and badly damaged in the front, a small wooden boat in the middle of the road, and what Mr Beddows described as a very rickety boat trailer a few metres behind it.
A family with two small children travelling north had escaped serious injury, he said.
The driver took evasive action but their car clipped the boat, and ended up in the drain on the western side of the highway.
