Motorists are still complaining about dangerous and baffling lane markings on Auckland's Northwest Motorway.

The remnants of old paint and cats' eyes are sending cars careering into different lanes, especially when driving into the sun.

After the media elevated the concern in October, the NZ Transport Agency carried out extra water-blasting and brought forward re-sealing of some sections.

SUPPLIED Shadow lane markings on Auckland's Northwest Motorway.

But comments on social media website Neighbourly show motorists still find it dangerous – particularly heading west around the Waterview Connection.

Owen Milburn from Henderson says this section is "absolutely shocking" and "a complete mess of lines".

Recently he was driving into the sun and concentrating hard at staying in the centre lane when before he knew it he had drifted into the inside lane.

"Lucky there was no one beside or behind me. I saw markings going in every direction to the right, to the left, and straight ahead, markings intersecting and bi-secting at 45 degree angles.

"All just as bright as each other ... everywhere you look are markings," Milburn says.

"What does it take for someone to fix this!"

Ranui resident Yasmin Numan​ says the lane marks are still an issue after NZTA's remedial work, and she has had to swerve to avoid a collision.

"Honestly, not sure if I was in the wrong lane or the other person was," she says.

"I find it ridiculous that so much money goes into all this construction yet there's no paint technology to use ... to avoid this deathly mess!"

Te Atatu South motorist Michelle Bishop says she has also had a few near-misses swerving into other lanes on several occasions over the past few months in glare or heavy rain.

"It has been an accident waiting to happen!"

Sandra Hickey agrees that the markings are terrible and confusing.

"I am glad this has been brought up, I thought it was just me," she says. "Hope it gets sorted real soon."

The Northwest Motorway is being widened and is due to be completed by the time the Waterview Connection opens early in 2017.

NZTA's Brett Gliddon​ has emplored motorists to stick to the reduced 80kmh speed limit while it is resealed over the next few months.

But motorist Roger Evans from Ranui posted on Neighbourly that the decreased speed limit is never enforced, "and a large number of Westie drivers are ignorant or simply arrogant in flouting it".

"Try driving to town at 5.30am to 6am at 80kmh and it is like being a rock in a river – everything else is zooming past," he says. "Slow down guys!"

Handerson Valley's Sonia Veelenturf posted that she has found a solution to the motorway confusion.

"I gave up and now catch the train, cos it's too stressful."
