Ports Authority Tonga Invests in New Street Sweeper to Support Green Ports Initiatives

Issued: 3rd September 2025 - Ports Authority Tonga (PAT) has taken another significant step forward in its Green Ports initiatives with the procurement of a new Dulevo 850 Environmental Sweeper from NZ Supplies Ltd, at a total investment of TOP $223,366.21 under PAT’s FY2024/25 Capital Expenditure program. The new sweeper will be used to maintain cleanliness and environmental standards across PAT’s operational areas, particularly at the Taufa’ahau Tupou IV Domestic Wharf (TTIVDW) and the Queen Salote International Wharf (QSIW) following recent upgrades.

Although diesel-powered, the Dulevo 850 EU6 – Tier 4 model is fully compliant with the latest Euro 6 (European) and Tier 4 (U.S.) emission standards. These standards are designed to minimize harmful nitrogen oxides (NOₓ), particulate matter (PM), and other emissions, while also meeting legislative requirements for gaseous and noise emissions. This makes the sweeper environmentally safe and consistent with PAT’s sustainability goals.

As part of the supply contract, onsite training was delivered by two technical experts from NZ Supplies Ltd, who visited Tonga last week to conduct a four-day program (Tuesday–Friday) for both PAT operators and mechanics.

On 1 September 2025, PAT officially commissioned the new sweeper. The occasion was marked with a blessing ceremony conducted by Father ‘Epeli Manisela of the Catholic Church of Ma’ufanga, who prayed for the safe use of the equipment and those who will operate and maintain it.

The event was attended by PAT’s Executive Management- ‘Alo Maileseni, Halloween Kisina and Mele Lavemaau, including the GM Administration- Lu’isa Lapao’o and the Manager Operations – International Wharf- Finau Mohu, who was also trained as an operator.

Chief Executive Officer of PAT, Mr. ‘Alo-ki-hakau Maileseni, stated:

“This investment demonstrates PAT’s ongoing commitment to modernizing our port facilities while upholding our Green Ports initiatives. The new sweeper will not only enhance cleanliness and safety at our wharves but also ensure compliance with strict international environmental standards.”

This investment was fully funded from PAT’s own cash flow, reaffirming the Authority’s financial strength and commitment to sustainable development.
