3 Executive Summary This report documents the volume and type of traffic moving within the waterspace between Princes and Wynyard Wharves as recorded in a marine traffic survey. It includes marine traffic accessing Viaduct Harbour and the NZ Maritime Museum, as well as vessels travelling between Westhaven Marina and the outer Waitemata Harbour. The survey covers a weekday/weekend period which is expected to provide an indication of average harbour traffic over late spring. The monitoring period was from Friday 24 th to Monday 27 th November The daylight hours survey observed low numbers of vessels in the waterspace between Princes Wharf and Wynyard Wharf. Out of almost 3,000 vessels counted crossing a survey reference line between Halsey St Extension Wharf and the North Shore, only 50 (1.7%) crossed within the Princes Wharf-Wynyard Wharf waterspace, an average of 1 vessel per hour over the survey period // NZ // page ii

5 1 Introduction 1.1 Report Context Panuku Development Auckland (Panuku), as lead delivery agency, has been tasked with providing waterfront infrastructure to host the 36 th America s Cup (AC36) and associated regattas in Auckland in Beca Limited (Beca) has been commissioned by Panuku to undertake technical studies on the existing physical environment and the effects of the proposed development for the resource consent application, as well as concept engineering design for the AC36 infrastructure. To document this work, Beca has prepared a suite of reports: America s Cup 36 Base Infrastructure Technical Report. America s Cup 36 Geotechnical Technical Report. America s Cup 36 Groundwater Technical Report. America s Cup 36 Preliminary Site Investigation (Contamination) and Remediation Action Plan. America s Cup 36 Coastal Processes and Dredging Technical Report. America s Cup 36 Stormwater and Services Technical Report. America s Cup 36 Traffic and Transport Technical Report. America s Cup 36 Fire and Evacuation Assessment. America s Cup 36 Marine Traffic Survey (this report). America s Cup 36 Engineering Concept Drawings. Reports by other specialists for the resource consent application cover: Landscape, visual impact and natural character (Boffa Miskell). Urban design (McIndoe Urban). Ecology, sediment and water quality (Golder Associates). Noise and vibration (Marshall Day Acoustics). Navigation and recreational vessels (Navigatus). Economics (Market Economics). Risk (Sherpa Consulting). Planning (Unio Environmental). 1.2 Purpose of Report The purpose of this report is to establish the volume and timing of marine traffic moving through the Waitemata Harbour during early summer, and particularly the volume and type of traffic in the waterspace between Princes and Wynyard Wharves where the wharf extensions and AC36 activities are proposed. The information provided by the survey will provide an input to the assessment of potential impacts on waterborne traffic in the vicinity of the proposed development. The report forms part of the resource consent application for the proposed AC36 development // NZ // page 1

Section 2: Methodology, which gives an overview of the survey approach. Section 3: Results sets out the results for the late November survey Appendix A: Survey data // NZ // page 2

7 2 Methodology 2.1 Location The location of the survey area is shown in Figure 1. Starting at Halsey St Extension Wharf, a reference line across the Waitemata Harbour between Halsey St Extension Wharf and the North Shore has been divided into two zones: a southern zone comprising the Princes Wharf- Wynyard Wharf waterspace; and a northern zone which covers the remaining distance to the North Shore. Dotted line delineates northern and southern zones Reference line Figure 1: Survey location and reference line 2.2 Survey Details This report covers late spring weekday/weekend period which is expected to provide an indication of average harbour traffic. The monitoring period was from Friday 24 th to Monday 27 th November In the past, marine traffic surveys have been completed by observers set at strategic locations around the Waitemata Harbour. Modern data capture and processing technology meant that it was more practical to employ a video recording survey for the 2017 surveys. This included the use of a security camera located on Halsey St Extension Wharf, which was directed so that it captured the movement of vessels from the wharf across the Waitemata Harbour. With the use of an annotated video playback, a reference line based on specified axes were used to delineate the northern and southern zones. The video footage from each survey was then analysed by counting vessels as they passed through the reference line set between Halsey St Extension Wharf and the North Shore, with // NZ // page 3

8 each vessel being identified as either in the northern or southern zone. The total number of vessels crossing the reference line was recorded in hourly increments. It includes the marine traffic accessing Viaduct Harbour and the NZ Maritime Museum, as well as vessels travelling between Westhaven Marina and the outer Waitemata Harbour. Surveys were completed between the daylight hours of 08:00 and 20:00 hours each day. The type of vessel was recorded, with seven categories being used: Ferries and cruise ships Yachts and charter yachts Motorboats including jet skis Tankers Small commercial vessels (tugs and fishing vessels) Kayaks/paddle boards Unknown/other (other including seaplanes etc.). The first survey period was conducted on an average Friday to Monday period (i.e. not a holiday weekend), with the Friday/Monday expected to approximate the higher end of average marine traffic volume within the Waitemata Harbour on a working day and Saturday/Sunday capturing the weekend volume. 2.3 Weather and Tide Conditions Conditions during the surveys were good for Auckland early summer, being fine and warm. Tidal conditions were within normal neap tide ranges as shown in Table 1. Table 1: Tidal information (LINZ tide tables, 2017). Date Time Level (m Chart Datum) Tidal Condition 24 November Low tide High tide Low tide 25 November High tide Low tide High tide Low tide 26 November High tide Low tide High tide Low tide 27 November High tide Low tide High tide Low tide // NZ // page 4

9 3 Summary of Results The daylight hours survey observed low numbers of vessels in the Princes Wharf Wynyard Wharf waterspace (southern zone). Figure 4 shows the total vessels per day recorded crossing the reference line in this southern zone, which averaged 1 vessel per hour over the survey period. A relatively large number of motorboats (total of 16 craft, mainly during the periods and ) crossed the reference line within the Princes Wharf Wynyard Wharf waterspace on the Friday, generating the peak compared with the other days surveyed. Figure 4: Total daily number of vessels crossing reference line in southern zone, November Other observations: There was a small increase in the proportion of ferries crossing the reference line within the southern zone in the weekend. Seldom were there any yachts or charters observed crossing the reference line through the southern zone, the only occurrences were when entering/exiting Viaduct Harbour. No tankers or ships were observed crossing the reference line within the southern zone. There were no large vessels of this type berthing at Wynyard Wharf during the survey period. The only small commercial vessel observed within the southern zone of the reference line was on Friday. This was a fishing boat entering Viaduct Harbour. Only one kayaker was observed during the survey period, crossing the reference line within the southern zone while entering Viaduct Harbour. No other kayaker or paddle boarder was observed. A seaplane crossed the reference line in the southern zone on Sunday morning. There was no distinct pattern observed when considering all types of vessels. Out of 2,941 vessels counted crossing the reference line between Halsey St Extension Wharf and the North Shore, only 50 (1.7%) crossed within the Princes Wharf-Wynyard Wharf waterspace. The majority of these vessels were on Friday // NZ // page 5
