The holes that were added to the course are the par-5 14th and 15th. They are narrower than you'd like them to be; it's pretty easy for players to miss left into 14 fairway from 15 tee, to avoid the edge of the cliff.
I am fairly certain that today's #10 is a combination of two of the holes from the original course; actually I think #11 was new, too, and that it was somehow a case of making two holes out of three. I'm pretty sure the other lost hole was somewhere in the outward run, but can't remember where.
Here are Donal's details on the changes. The other lost hole is from the combination of 6 and 7 into the new dogleg 6th up into the dunes.
BEGIN DONAL
Here's a list of the alterations to N&P.
1st: Same as old 1st which was listed as 289-m on the card I have from 1980s/90s. Two fairway bunkers on left added.
2nd: Same as old 2nd hole, listed as 450-m. Five bunkers added down the left hand side; the first two added after 2005. The last three added sometime in late 1990s. One bunker that was between the green and the lake was removed prior to 2000. If you played this hole in the 1990s or earlier, you will remember a big fence running across the 17th and 2nd fairways. Cattle grazed on the south part of the course. The 1st, 17th and 18th greens used to be surrounded by electric fences.
3rd: Same as old 3rd, listed as 171-m. There was a bunker between the green and the drain (OOB) on the right, but this was removed in late 1990s.
4th: Same as old 4th, listed as 416-m. Old green was about 50 yds left of present green, so the drain was never a danger. New green now tucked into the corner bringing drain and OOB more into play. All four bunkers are new.
5th: Same as old 5th, listed as 356-m. Two fairwary bunkers added and a greenside bunker (on front right) removed.
Now we get to the first major change.
6th: This new hole is a composite of the old 6th and 7th holes. The old 6th was a par 3 of 187-m played in the same direction as the drive for this new 6th hole. The old green was/is located where the hole doglegs left. It wasn't that memorable a hole, so I do not think N&P is any worse off as a result of its loss. The old 7th hole played (292-m) from a tee to the right of the turn of the dog-leg. It was an uphill par 4 to a green about 50 yards beyond the present new 6th green. It was a really tough green to hold, especially in the wind. The green was/is located on the left side of the present 10th fairway.
Here's a photo of the old 6th green, as viewed from front left; the old ladies 7th tee is in the background:
Here's a link to the old 7th green, with the old 12th green in the background:
7th: Same as old 8th, listed as 130-m.
8th: Same as old 9th, listed as 294-m. The little green just to the south of the main green was there in the 1990s or even earlier. I never saw it in operation and I wonder why it was developed.
9th: Same as old 10th, listed as 356-m.
So, it may come as a surprise, but not so much has been changed on the first nine. I'm not sure, but the first green may have been redone. The 4th and 6th greens are new; the rest on the front nine are unchanged I believe.
10th: New hole which follows the routing of old 11th and 12th holes. The old 11th was a par 3 of 180-m which was played from the present 10th tee in roughly the same direction as the drive for the new 10th. The green was located at the right edge of the present fairway. It was a tough par three with anything slightly left running down the side into a hollow. Sand being blown in from the beach was a constant problem in the winters. The whole hole, including the present 9th green were constantly being dumped with sand. The old 12th hole - a par 4 of 303-m - played along the present hole. The mens tee was located just below the current 8th tee. The green was situated into the left about 100 yards short of the current green; before the fairway pinches.
Here's a link showing the old 11th green:
11th: A new par 3 to replace the old 13th which was also a par 3. The old 13th was 170-m and ran almost parallel to the present hole. The tee was located very close to the current tee box and you played directly over the current 12th green. When you walk from the current 11th green along the path to the 12th tee, you pass through an open area with short grass; this is where the old 12th green was situated.
Here's a not so great photo of the old 13th:
12th: Same as old 14th which as 476-m on my old scorecard. Two greenside bunkers removed and one added about 70 yards short of the green on the left.
13th: Same as old 15th which as listed as 450-m. One greenside bunker on the left removed.
14th: New hole.
15th: New hole.
16th: Same as old 16th. One greenside bunker on the left side removed.
17th: Same as old 17th, listed at 371-m.
18th: Same as old 18th and listed as 321-m. The green was relocated about 30 yards to the right, probably for safety reasons. It was always a pain having to wait on the first tee while players finished out on the 18th green. This is no longer a problem. There are two new fairway bunkers down the left and three new ones on the right of the new green.
