Retailers in Lower Hutt have reported loss of income and even closure, as roadworks in the city centre take too long to finish.

Local authorities have carried out multiple projects to future-proof service infrastructure, improve flood protection, develop the CBD and improve transport connections.

As part of the work, the road at the Queens Drive/High Street intersection has been shut starting March 2 and will run until December.

The construction has caused gridlock and delays, affecting the operations of many businesses.

Jinuka Paranavithana, who runs Lakdiv Supermarket in the area, told Radio NZ that his business revenue has dropped 50 per cent since the works began.

Paranavithana is now looking for leases elsewhere, saying that his supermarket would not last until the works are completed.

A nearby kebab shop has been shuttered for good, after the owner reported a 50 per cent drop in business and was getting into debt.

The construction is also shutting down another stretch of High Street for four weeks. Patrick Gao, who owns the nearby City Green fruit and veggie shop, has also seen a significant decline in takings.

Gao thinks he can stick around another month or two, and has put out a plea on social media, asking for local support to help get him through.

Many locals told Radio NZ that the roadworks were necessary, but too much was being done all at once.

Meawnhile, Greater Wellington Regional Council transport committee chair Ros Connelly said disruption was certain no matter how the work was carried out, and the parties involved had chosen “the most efficient work program from a cost perspective and also from a logistics perspective”.
