	Recovery and relocation of native fish We are working hard to protect native freshwater fish in the ecologically fragile streams along SH20B. Using specialist techniques with some help from our friends at Bioresearches, we carried out native fish recovery over four days and three nights in early March before our invasive earthworks started outside Manukau Memorial Gardens. Our team used sandbags and cloth to form downstream and upstream barriers. Four Marmite baited (yes really!) fyke nets and twelve Marmite baited minnow traps were used to lure fish into an area where they could be safely collected.



	76 fish safely recovered and re-homed A total of 76 fish were safely recovered from the outlet pool and no fish were injured! These include inanga (Galaxias maculatus, shown above), shortfin eels (Anguilla australis) and banded kōkopu (Galaxias fasciatus). They have been successfully re-homed 200 metres down the stream and are now enjoying their tranquil lives away from our heavy machinery. Their new home was specially selected for its deep pools and overhanging vegetation.

	Introducing our on-site Safety and Environment Manager Karol Brooks Karol ensures all construction staff at SH20B know the rules - from what to wear (PPE), to specific safety and environmental compliance. In the last 127 project days she has led more than 150 on-site staff inductions at SH20B. She always encourages all members of the team to assess and report risk and `think smarter' about how to operate. With a varied background in operations management along with time spent raising and caring for family, Karol has been working in safety and improvements for more than 17 years. “I enjoy every moment of my job and I particularly enjoy the sense of connection and engagement across different teams here at SH20B. As individuals, we all want to go home safely at the end of each day. We also have a responsibility as part of a team to be leaders in safety and looking after the environment. I get huge satisfaction from being able to offer guidance and leadership to all our people whether they are responsible for holding a stop/go paddle or leading the team in solving complex engineering issues.”

	Project overview


	Waka Kotahi NZ Transport Agency and Auckland International Airport Limited are upgrading State Highway 20B for better and more reliable travel options with a new shared path and additional priority lanes between Pukaki Creek Bridge and State Highway 20. This project will integrate with improved transport facilities within the airport precinct along SH20B and at the upgraded Puhinui Station Interchange. The project is the first step of the Southwest Gateway programme to provide better public transport, walking and cycling facilities with safer and more efficient freight movements to, from and around Southwest Auckland. Fulton Hogan undertakes this work on behalf of Waka Kotahi. Key early improvements on State Highway 20B to be delivered by 2021 include: A safe place for people to walk and ride bikes Safety improvements including central median barrier protection, improved lighting and a reduced speed Improved pavement, drainage and stormwater treatment Two improved intersections at Campana Road and Manukau Memorial Gardens. Waka Kotahi NZ Transport Agency works to create transport solutions for all New Zealanders – from helping new drivers earn their licences, to leading safety campaigns to investing in public transport, state highways and local roads.
