A report prepared for today's committee meeting said council staff believed the overnight vehicle ban was necessary to fully achieve safety measures outlined in a crash reduction study carried out last year.
Only the minimum length of guard rail recommended by the coroner had so far been installed and straight sections of the upper peak road remained unprotected.
But the two safety proposals being recommended to the committee have been met with a mixed response from the Te Mata Park Trust Board, which is opposed to extending the railing.
In a letter to the council last month the trust said it supported restricted vehicle access at night but "strongly opposed" further barriers on the upper reaches of the road to the summit.
It was concerned the barriers would prevent pedestrians and cyclists from moving out of the way of vehicles and that they would also trap sheep on the road.
Trust chairman Bruno Chambers said yesterday that with an analysis showing 60 per cent of accidents on the road happened during the hours of darkness, but with only seven per cent of traffic using the road between 7pm and 7am "there's quite a strong argument for closing the road" at night.
Mr Chambers said the trust was happy with the council's moves to date to improve safety on the road but it believed the proposed barrier extension was "overkill" and it would instead be better to install barriers at two high-accident corners below Peak House restaurant, at the lower end of the road.
The council recently voted to cut speed limits on the road. The previous limit up to the Te Mata Park car park was halved from 100km/h to 50km/h. A section from the carpark to halfway to the summit was cut from 50km/h to 40km/h and the final climb to the summit was dropped from 50km/h to 20km/h.
