The Changing Landscape of Development - Land Development Engineering Forum 2022

The LDEG Forum took place from 17-18 November 2022 in Tauranga. 

The ever changing procurement and resourcing market are adding to the complexities of our industry, creating an uncertain future for councils and developers. How will our landscape look in six months? A year? Five years? 

We need to address the challenges of historical infrastructure under investment, significant demand on our infrastructure, ongoing population growth and communities grappling with climate change. This forum will discuss these issues and prompt delegates to be mindful of how to approach our changing landscape of development.

Changing how Tauranga's streets are designed

Natalie Rooseboom & Sarah Dove

About Natalie & Sarah

Natalie is Tauranga City Council’s Manager for Asset Services and looks after teams that cross over the entire lifecycle of assets. These teams include infrastructure development code, land development engineers, and monitoring advisors who focus on the detail, design and construction phase of assets, and the asset information and planning teams that support activities in operation, maintenance and renewal planning. 

Natalie is a civil engineer with more than 20 years local and international experience and with a master’s degree in engineering studies, specialising in sustainability, from Auckland University.

Sarah worked on the Tauranga Street Design Guide project during her previous role, and is now championing utilising the Guide and Tool within TCC on a variety of transportation projects.


How do we go about ensuring the future streetscapes of one of New Zealand’s fastest growing cities meet the needs of people now and in the future?

In Tauranga the Infrastructure Development Code (IDC) defines how streets are designed. Historically this has been a ‘standards’ focused process which lacked the ability for ingenuity. Tauranga City Council wanted to ensure new streets, and street upgrades, could be designed in a way that allowed streets to have more of a place function rather than being focused on vehicle movement. It was also important to, allow developers/ street designers to have the flexibility to design streets in a way that they wanted, whilst still achieving TCC’s outcomes.

Our presentation will explain how the project team achieved this and what were the challenges and trade-offs they experienced along the way.

Safe might be safe but it's not always sound! Anticipating resource management reform

Alice Balme, Wynn Williams

About Alice

Alice is a partner in Wynn Williams’ Environment + Planning team, specialising in resource management and local government law. With extensive knowledge of both environmental management and local government processes, Alice is regularly engaged to advise clients on contentious resource consent and district plan matters. She is frequently sought out to assist with consenting infrastructure projects  – working with project teams from the inception of an idea through to project delivery.


Reform of the Resource Management Act has long been anticipated by all involved in land development, not least of all those charged with the responsibility of servicing these communities 30 or 40 years into the future. Those expecting reform will deliver a single silver bullet that provides certainty to move forward with confidence are sadly mistaken. What you can be confident of is a cascade of transformative and systemic change involving not just the RMA but three waters and local government reform. In 12 months’ time, everything could be different – but how is virtually impossible to anticipate. The obvious question then becomes how do we continue our BAU in the absence of clear, cohesive and prescriptive guidance? Answer – play it safe and rely on what we know to stand us in good stead. Perhaps the better question is what can we be doing to ensure we’re able to successfully ride the wave of change and, even better, get ahead of it?

The real ‘Dirt’ on Land Development

Mike Speed, Bay Civil Limited

About Mike

Mike Speed is GM of a small to medium sized Tauranga based civil contracting firm known as Bay Civil Limited. His life experience in Construction across the North Island, and with influences from his time in Melbourne, Australia, give him a unique view of how the land development sector has evolved and grown, and the challenges that today’s landscape presents. 


Land Development Engineering is more than just creating a “vision” of a project on behalf of a client. In today’s world you’ll need to demonstrate the engineering science behind the concept, how it supports or enhances the surrounding environment and how it ties into the city (or regional) plan. Then there’s the consideration of cultural requirements and restrictions, and the valuation of the project – is it even feasible? So much to consider…

In this talk, Mike Speed – a Civil Contractor with 25 years in the industry explains the game from a different perspective – and from an angle that is at times possibly not as well prioritised as it could – or should be.

Mike will touch on the challenges – and rewards, associated with land development construction in the field that he knows so well – the sandy soils of Papamoa.

Working with the land and natural hazards - the need to accept some inconvenience

Marianne O'Halloran

About Marianne

The increasing population is pushing development onto steeper land and that subject to liquefaction, settlement and flooding.  This, in addition to the challenges brought about by climate change and the need to reduce the whole of life embodied carbon in construction, means that we need to think about how we can work with our environment instead of trying to control it. 

Are we prepared to climb steps to our front doors and to wear gumboots to walk home occasionally?


Marianne began work in the Special Projects Office of the Ministry of Works following completion of a PhD in civil engineering specialising in geomechanics.  She moved to Tauranga after 11 years working on investigation, design and construction supervision with the Ministry and its successors.  In Tauranga she worked for eight years with a consulting company that was involved with the planning, design and construction of many infrastructure projects. Since 2002 she has been working as a sole geotechnical practitioner carrying out a lot of work for regional, district and city councils in addition to private companies and individuals throughout the central North Island.

Marianne and her husband also had a small civil construction company for over 20 years that specialised in difficult access work, bridge, dam and tunnel repairs and the maintenance and construction of structures for the Department of Conservation.  She was one of the first Urban Search and Rescue (USAR) engineers in New Zealand and worked with them for 17 years.  Through this organisation and her connections with the councils she has been involved with the responses to numerous landslides, storms, floods and earthquakes.

NZS4404 is an outdated standard that is still in use today by many Land Development Engineers.  With the likely 3 Waters Reform on the horizon, what will be the future of NZS4404?  This presentation looks to explore the options for progressing updated standards to the industry while considering the approach taken by the National Transition Unit as part of the 3 Waters Reform process.

Transitioning asset management through Three Waters reform

Emily Botje, Asset Management Lead, National Transition Unit, Department of Internal Affairs

About Emily

Emily is the Asset Management Lead for the National Transition Unit and is instrumental in helping to establish the four new water services entities that will deliver Three Waters Reform across the country.

Emily joined the team in June of this year and is primarily responsible for:

  • the development of asset management plans for each entity, including the 10-year capital investment plan
  • a national code of practice for reticulation design and construction
  • frameworks to support growth, and
  • maintaining infrastructure investment through transition

Emily has been working in the asset management space for 25 years with local and international experience and brings with her a wealth of knowledge in the infrastructure management space.


Three Waters Reform is a once in a lifetime opportunity to transform three waters services for the health and wellbeing of generations to come. Te Mana O Te Wai will be at the heart of the new system, which will underpin a catchment-based approach to managing water services.  The reforms will also deliver scale and balance sheet separation, enabling the new entities to raise much greater levels of debt to fund the investment required, to be paid back over a longer timeframe (helping with affordability).  Reforms also create the opportunity to build and sustain a highly skilled and adaptable water workforce and a customer-focused business that leverages new technologies and creates awareness of the water system and the value of water. The presentation will explain how asset management plays an integral part in making this happen.
